Thanks for your feedback.
I’ve been testing OTC on a very old version of OG for a week now. I did experience connection loss a few times, but somehow as I keep trying the cloud connection eventually comes back (though local connection doesn’t always come back). So it looks like when connection is lost it’s not stuck forever. I will have to do some more debugging to check what’s going on. It might also have to do with the fact that I have a very old version of OG. Need to test it on a more recent version of OG as well.
