I have installed erpnext V13 on AWS EC2 and I am trying to add an email domain but it is always giving me a “Not Saved” without any log.
I checked the chrome console and I found the below issue once I am loading the page.
/socket.io/?EIO=3&transport=polling&t=NcMbw0K:1
Failed to load resource: the server responded with a status of 404 (NOT FOUND)
I tried to npm install socketio but nothing has changed. Even I did bench update but nothing has changed also.
Do you know how to fix that?
