I was double checking my router config and noticed the port forwarding was set to both TDP and UDP on 51820. On a whim I changed it to UDP only and amazingly it worked!
I actually never thought that setting the port open with TCP and UDP could cause this problem. It never occurred to me to try that to see what would happen ![]()
I've added a new common issue to the wiki. https://wiki.omv-extras.org/do…nfiguration_on_the_router
