Creating a new session worked this time. In fact, it is connecting faster than usual. I also notice the Zeus wallet GUI now has a direct LNC option. I think it required LND rest before? It's been a while since I had problems with the connection, so perhaps it has been this way for a while. I also updated Lightning Terminal. That could also have been the issue?
I can imagine that the session may have expired, or that indeed some upgrades on the Zeus or litd side caused the old connection to break. Glad it's working now!

Anyway, thanks for your help.
