I’m trying to run Bisq 1.95 (just updated) on a Mac running OS10.14.6. Bisq ran fine on this machine in the past, but now I can’t make a connection.

Don’t know if the screenshot will be visible, but it says, "Connecting to the Bisq network failed (reported error: error reply: invalid key type). Please check your internet connection or try to restart the application.  
".  
My internet connection works fine for everything else and I tried restarting the app numerous times to no avail.  
What does this mean and how can I fix it?  
All help greatly appreciated.  
Ted

1. Create a Backup. [Backing up application data - Bisq Wiki](https://bisq.wiki/Backing_up_application_data)
2. Stop Bisq if it was running.
3. Remove Tor files, except hiddenservice. [Data directory - Bisq Wiki](https://bisq.wiki/Data_directory#Default_Locations)
4. Start Bisq.

Thanks for the help.  
I backed up the bisq folder: deleted everything in the original tor folder except the hidden services folder: and restarted Bisq. Same error message. The only difference is that it took only about 30 seconds to appear. Before it took a few minutes.  
What else can I try? Should I reinstall Bisq?  
All help greatly appreciated.

It’s possible there are issues with your tor key, actually. So let’s try this:

- stop Bisq
- rename the whole `tor` folder in data directory to `tor.old`
- start Bisq

This will get you a new onion address though, so be warned ongoing trades will not work correctly, if any
