Common Surfshark problems and how to fix them
Most Surfshark problems fall into a few areas: a connection that will not establish, speeds that drop, a device that keeps disconnecting, a site that blocks the VPN, or an app that will not sign in. Here are the ones that come up most, and what to check first.

TL;DR
- A connection that will not start is usually the protocol, the network, or the app itself.
- Slow speeds often come down to server distance and load.
- Sites that block a VPN are detecting the server, not your account.
- Kill switch and split tunnelling settings explain many odd disconnects.
- Check the exact step that failed before you reinstall anything.

Why things go wrong
Surfshark runs on top of your normal connection, so a fault can sit in the app, in the network in front of you, or in the server you picked. The useful first move is to work out which layer is failing.
Another habit that saves time: try a different network and a different server. If the problem follows the server it is not your device, and if it follows the network it is not the app.
Will not connect
When the app sits on connecting or drops straight back to disconnected, start with the protocol. Switching from automatic to a manual choice often unblocks a network that filters VPN traffic.
Then check whether the network allows VPNs at all. Some office, hotel and campus networks block the ports a tunnel needs, which is why a mobile hotspot can work when Wi-Fi will not.
Slow speeds
Speed drops are usually about distance and load. A server on another continent adds latency, and a busy server shares its bandwidth with more people.
Pick a nearby location, try the fastest-server option, and test the same site at two different times of day to see whether load is the cause.
Keeps disconnecting
Random disconnects are often the kill switch doing its job on a flaky line, or a device switching between Wi-Fi and mobile data.
Check the kill switch and auto-connect settings, and note whether the drop happens when the network changes rather than at random.
A site blocks the VPN
Some sites detect traffic from known VPN ranges and block it. That is about the server address, not your account, so the fix is usually a different location.
Try another city or country for that site, and avoid reconnecting and retrying too fast, which can look like automated traffic.
Cannot sign in
Sign-in failures are usually the password, a two-factor prompt, or a device limit rather than the tunnel itself.
Confirm the credentials, check the two-factor app, and review how many devices the account is already using.
Symptom to fix
| Symptom | Likely cause | Fix |
|---|---|---|
| Will not connect | Protocol or a restricted network | Switch protocol, then try another network |
| Slow speeds | Server distance or load | Choose a nearby or fastest server |
| Keeps disconnecting | Kill switch or network switching | Review kill switch and auto-connect |
| Site blocks the VPN | Server address is flagged | Try a different location |
| Cannot sign in | Credentials, two-factor or device limit | Reset the password, review devices |

Frequently asked
Can I fix these problems myself?
Many of them, yes. Protocol, server choice and app settings are in your hands. Server-side faults need a support ticket.
Why does my connection drop on one network only?
That network is likely blocking the tunnel or switching you between Wi-Fi and mobile data. Try another protocol or a hotspot.
Does the kill switch cause disconnects?
It can look that way. The kill switch cuts traffic when the tunnel drops, so a flaky line shows up as repeated disconnects.
Why can I not open one specific site?
That site is probably detecting the server address. Choose a different location and avoid rapid retries.
