Unable to connect to eclair nodes

[yo-mr-white]

Issue and Steps to Reproduce

It looks like that I am not able to open a channel to eclair nodes from my CLN. I tried few LND/CLN nodes and everything was fine.

However when I tried connect for example to ACINQ, I am getting this error:

lightning-cli connect 03864ef025fde8fb587d989186ce6a4a186895ee44a926bfc370e2c366597a3f8f@3.33.236.230:9735

}

The same issue with 023631624e30ef7bcb2887e600da8e59608a093718bc40d35b7a57145a0f3db9af@52.27.151.162:9735 (also eclair).

The node is running quite old version (v0.12.1) but the upgrade is scheduled.

Is this related to old version or there is some incompatibility between CLN and eclair right now?

Thank you

• v0.12.1 is very old. It has known issues that were fixed a long time ago.
• v23.05.2 was working well with the ACINQ peer. This is the currently recommended stable branch.
• v23.08rc1 had a problem but it was fixed in the master branch.

Please use v23.05.2 and report back.

Upgraded to v23.05.2 and it's working, thanks!
