Hi @siarheicts,

Thanks for your report. Could you please add some more details of your situation:

• which loop version are you running?
• did you recently update your loop version
• have you tried restarting the client? Does it result in the same errors?
• was there any action you can think of you took that might cause a problem?

Thanks for you help.

loop version - 0.29.0
lnd - 0.18.5-beta
The problem appeared after restarting Lightning Terminal; restarting does not help, and reinstalling does not solve the issue either.

@siarheicts The patch is merged into Loop master branch.
If you run Lighting Terminal, you could disable the integrated Loop in Lightning Terminal for now by passing --loop-mode=disable flag to your litd daemon.

Then you can manually build Loop from master:

git clone https://github.com/lightninglabs/loop.git
cd loop
make install

(You need Go at least of version 1.23.6.)
It will put loopd and loop files into $GOPATH/bin directory.

Then run the loopd binary. Please tell if it works for you!

[starius]

When Lightning Terminal with this fix is released, you can switch back to using integrated Loop mode. If you want, you can use remote mode in Lightning Terminal until that.

[siarheicts]

Thank you for the quick solution.

[starius]

The issue is resolved.
