By following a systematic approach, you can pinpoint whether the issue stems from software, hardware, or network restrictions. The steps outlined here are tailored to help you navigate error code 86101 and related connectivity challenges.
While this guide focuses on the Proton VPN error code 86101, it also addresses broader Proton VPN troubleshooting scenarios, including iOS-specific errors and corporate network blocks. By the end, you’ll have a clear roadmap for resolving the most common connection issues.
Step‑by‑Step Instructions
1. Verify the Error Code Across Devices
First, confirm that Proton VPN error code 86101 is consistent across multiple devices. If only one device shows the error, the problem is likely local to that device. If the same code appears on phones, laptops, and tablets, the root cause probably lies with the network or service.
Open the Proton VPN app or the web client to see the error details. Take note of any accompanying messages, such as “Connection timed out after 30 s.” This information is crucial for diagnosing the underlying issue. Document the exact wording, as it can guide you through the next troubleshooting steps.
During this verification, you might also see other error codes like “0x43524f54” on iOS or “ERR_CONNECTION_TIMED_OUT.” These variations can hint at platform‑specific configurations that need adjustment. If you encounter such codes, check the dedicated iOS error guide: Proton VPN error 0x43524f54 iOS.
2. Confirm Your Internet Connection
Before diving into VPN settings, ensure your base internet connection is stable. Use a browser to load several high‑traffic sites. If you experience slow load times or frequent disconnects, the issue might be your ISP or Wi‑Fi router.
Resetting your router can resolve many transient issues. Simply unplug it, wait 30 seconds, and plug it back in. This action clears the router’s cache and may eliminate hidden firewall rules that block VPN traffic.
For travelers using hotel or public Wi‑Fi, the network may restrict port usage. Test your connection by turning on Proton VPN, then accessing a website like Cloudflare Learning. If the page doesn’t load, the network may be blocking necessary ports.
3. Update the Proton VPN Application
Running an outdated client is a common cause of Proton VPN error code 86101. Open the app’s settings or help menu and select “Check for updates.”
Download and install any available updates. New releases often fix bugs, improve compatibility with newer OS versions, and patch known timeout issues. After updating, restart the app and attempt to connect again.
On Windows, you may also want to reinstall the Proton VPN client. Uninstall it from “Add or Remove Programs,” then download the latest installer from the official site. This clean install can resolve corrupt configuration files that lead to timeouts.
4. Adjust DNS Settings
DNS misconfiguration can cause the VPN handshake to stall, resulting in a timeout. Open your device’s network settings and switch the DNS to a public resolver like 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare). This ensures that DNS queries are resolved quickly, allowing the VPN to establish a connection.
For more detailed troubleshooting, consult the Proton VPN article on error code 86101: Proton VPN error code 86101. It explains how DNS caching can interfere with the handshake process.
On macOS, use “scutil –dns” to view current DNS servers, then edit the network preference pane to set manual DNS entries. After saving, run “dscacheutil -flushcache” to clear the DNS cache.
5. Modify Connection Timeout Settings
Some Proton VPN configurations allow you to adjust the connection timeout. Navigate to the app’s settings, locate the “Connection” or “Advanced” section, and look for a “Timeout” or “Connection timeout” field.
Increase the timeout value from the default (typically 30 s) to 60 or 120 s. This change gives the client more time to negotiate with the server, which can resolve issues on slower or congested networks.
Remember to revert the setting back to default once the issue is resolved to maintain optimal performance. The higher timeout can slightly slow the connection initiation on stable networks.
6. Switch to a Different Server
Proton VPN offers multiple servers worldwide. If one server consistently triggers Proton VPN error code 86101, try selecting a server in a different region. In the United States, servers in Atlanta or Dallas often provide better connectivity compared to those in the Midwest.
When choosing a server, look for the “Ping” or “Latency” indicator. Selecting a server with lower ping reduces the likelihood of a timeout during the handshake phase.
In Europe, if you’re in Germany, test servers in Frankfurt or Munich. For users in Brazil, opt for servers in São Paulo. Switching servers is a quick way to bypass local routing issues that might be blocking VPN traffic.
7. Disable VPN Protocol Switching
Proton VPN supports multiple protocols, such as WireGuard, OpenVPN, and IKEv2. If you’re experiencing timeouts, try disabling the protocol that the app auto‑selects. In the settings, manually choose WireGuard, as it generally provides faster and more reliable connections.
Some networks block older protocols like OpenVPN on TCP port 443. Switching to UDP or WireGuard eliminates this restriction. After changing the protocol, reconnect to see if the Proton VPN error code 86101 disappears.
For users on iOS devices, the protocol can be changed in the app’s “Settings” tab, then scrolling to the “Advanced” section. This tweak often resolves iOS-specific timeout issues.
8. Contact Proton VPN Support
If all previous steps fail, it’s time to reach out to Proton VPN’s support team. Use the in‑app “Help” menu or visit the official ProtonVPN support portal to open a ticket.
Include the error code, a description of your network environment (e.g., “public Wi‑Fi at a university”), and any relevant screenshots. The support team can investigate server‑side logs and provide a customized solution.
While waiting for a response, consider testing the VPN on a different network (e.g., a cellular hotspot) to confirm whether the issue is local or server‑based. This data will help the support team isolate the problem more efficiently.
Tips
Keep your VPN client updated. New releases often patch known timeout bugs and improve overall reliability.
Use a wired Ethernet connection when troubleshooting. Ethernet provides a more stable link than Wi‑Fi, reducing the chance of timeout errors.
Enable the “Kill Switch” feature. This ensures that if the VPN disconnects, your internet traffic is blocked, preventing data leaks.
Disable other VPNs or proxy software that might conflict with Proton VPN’s connection process. Multiple VPN clients can cause port conflicts.
Check for local network restrictions. Some routers block outbound ports used by VPNs; consult your router’s manual or support site to open those ports.
Use a different DNS provider like 1.1.1.1 or 8.8.8.8 to avoid DNS‑level blocks that can cause timeouts.
Test on a different device. If the issue is isolated to one device, the problem likely lies within that device’s settings or OS.

Alternative Methods
Use an OpenVPN Configuration File
If the native app fails, you can import a custom OpenVPN config file. Download the .ovpn file from Proton VPN’s portal and import it into a third‑party OpenVPN client.
OpenVPN clients allow manual configuration of DNS, routing, and security settings, which can bypass app‑specific issues that trigger Proton VPN error code 86101.
When importing, select “UDP” for the protocol and set the “Timeout” to 120 s. This gives the handshake ample time on slower networks.
Switch to WireGuard
WireGuard is a lightweight protocol that offers faster handshakes. Proton VPN’s WireGuard configuration files are available on the user portal.
After downloading the WireGuard config, install a WireGuard client on your device. Import the file and enable the connection. WireGuard’s simple key‑exchange mechanism reduces the likelihood of timeout errors.
WireGuard also supports “PersistentKeepalive” settings that help maintain a steady connection through NAT or firewall restrictions.
Use a Different VPN Provider Temporarily
For critical use cases, consider switching to a backup VPN service if Proton VPN remains unreachable. Providers like NordVPN, ExpressVPN, or Mullvad offer comparable security.
Set up a temporary profile that mirrors Proton VPN’s server choices in terms of region and speed. This allows continuity of service while you troubleshoot the error.
When you’re ready to return, simply switch back to Proton VPN once the timeout issue is resolved.
Check for Router-Level Blocks
Some corporate or institutional networks explicitly block Proton VPN traffic. Refer to the Proton VPN blocked article for steps to verify if the network is blocking the service.
In such environments, use a VPN that operates over port 443 or a stealth mode that masquerades traffic as regular HTTPS. This can bypass firewall restrictions that cause Proton VPN error code 86101 on restricted networks.
Contact the network administrator to whitelist Proton VPN or the ports it uses. This is often the most reliable long‑term fix on institutional networks.
Test on Mobile Data
Open the Proton VPN app on a smartphone and switch to the mobile data network. If the connection succeeds, the issue is likely with your home or office Wi‑Fi setup.
Use the “Mobile Data” toggle in the app’s settings to force a cellular connection. This is especially helpful in regions where public Wi‑Fi is heavily censored.
When using cellular data, be mindful of data usage. Proton VPN’s “Data Saver” mode can reduce bandwidth consumption.
