Hi, haven’t used Bisq for a while. Upon opening the application I get this error.

 ![Screen Shot 2021-05-10 at 2.02.25 pm](https://bisq.community/uploads/default/original/2X/2/21ecc752debd054de0bf8d690b6207e15bb2d1ef.png)

I’ve deleted the outdated files as suggested yet still doesn’t work.

Can you help please?

Thanks

Hi, network issues doesn’t usually have a simple solution. Try to:

- Restart Bisq after restarting the computer, and different networks, better if they’re fast.
- Make sure that your ISP is not blocking Tor by running the Tor browser.
- This troubleshoot guide has more delicate possible solutions. Most of the time just by re-trying you’ll get to start Bisq, but removing some Tor files is also quite helpful. Do a backup of the folder before removing any file. [Support Agent - Bisq Wiki](https://bisq.wiki/Support_Agent#Connection_issues)
