SSH key problem when connecting to self-hosted repo

Wappler: 5.6.2
OS: MacOS M1
Server Model: N/A

I’m now using a self-hosted version of Gitea instead of the mainstream providers and it’s working brilliantly. However, while my desktop mac is connecting perfectly, my macbook isn’t. I’ve set it all up exactly the same, a new SSH key which has been added to the gitea installation, but I keep getting this error when doing anything in the Wappler Git Manager:

I’m using the terminal to do fetch, pull and push and that works fine. Doing git fetch and then clicking on the refresh icon does the job but I’m posting this so it can be fixed in Wappler so it all works nicely again.
