Lost remote access

[bertsirkin]

This morning I had remote access to my BI server. I could access it on my LAN with a local IP address or from the WAN with a WAN IP address. Then suddenly, I lost access. Nothing was changed - nothing updated, rebooted or anything (at least on my part). When I look at the "local" LAN IP address, I see an IPV6 address on port 81 - I'm pretty sure, but not completely sure, this used to be an IPV4 address. The remote IP address is the correct external WAN IPV4 address on port 81. But, I can no longer access the BI server either locally or remotely.

Any suggestions appreciated!

unplug from the internet

Then try local login

No difference.

Well, I determined that it's a Windows firewall issue - I turned the firewall off and I can connect. I'm guessing there was an unattended Windows update, and that something changed in the Windows firewall. Once I opened up the windows firewall, I regained access.

Good to hear.

FYI You should access when remote via a VPN (like OpenVPN or WireGuard) and not port forward on the router
