Okay, so here is the case, we have an ERPNext server located in our office B location. And we are just connecting to it via internet.
It seems that our policy in our office A is only allowing port 8080, but blocks other ports that ERPNext is using. for now, we have allowed all ports for ERPNext access.
Please correct me if im wrong: Do we only need to allow ports 22, 80 and 3306 for ERPNext to function without errors/problems?
