Hey,

So I tried pointing Bisq to my own Nodl (nodl.local:50002). It wasn’t able to connect/synchronise with network, so I tried to delete SPV.

After deleting SPV, I got the option to delete outdated Tor files and shut down.

After doing so, I’m unable to startup Bisq at all. Just stuck on “Connecting to Bitcoin network” with 12 Bisq network peers.

Windows 10 and Bisq 1.1.7.

Thanks for any help and much appreciated

Things I’ve tried:

- reinstalling Bisq
- restarting computer
- disabling firewall and antivirus
- Tor browser confirmed working

I know I should migrate to Ubuntu, but it’ll be a lot of time for me to learn it.

Try to run Bisq with the following flag  
`--btcNodes=[]`

> <https://github.com/bisq-network/bisq/issues/3137>
>
> \[How to Reproduce\]
> 1) Go to Settings -\> Network
> 2) In the Bitcoin P2P node con…figuration under "use the following Bitcoin nodes", enter an invalid or unsupported hostname , such as the Tor v3 hostname 32zzibxmqi2ybxpqyggwwuwz7a3lbvtzoloti7cxoevyvijexvgsfeid.onion:8333
> 3) Bisq indicates it must be restarted, click OK
> 
> \[Expected Results\]
> After Step 2, Bisq should validate the hostname is a valid Tor v2 hostname using regex or some other method, and also attempt to connect to this node. If it cannot validate or connect, it should not allow this setting to be changed, and it should not instruct the user to restart Bisq.
> After Step 3, Bisq restarts, and despite the Bitcoin node being unreachable, the user should be able to proceed and reconfigure their settings to a reachable Bitcoin node.
> 
> \[Actual Results\]
> After Step 2, Bisq did not perform any validation or testing of the user-entered hostname, it allowed the user the proceed, and it requested the user to proceed and restart Bisq.
> After Step 3, Bisq restarts, but because the node is unreachable the following error is displayed and user is stuck with no way to correct their Bitcoin node settings, as they cannot get to the configuration screen.
