NetExtender not connecting but RDP connects


before writing, I have gone through several suggestions including:

I have Windows 11 and NetExtender 10.2.337

Error message is 0x000A0318 The Server is not reachable. The Server May be down...

However, I can reach the Virtual Office portal, click the bookmark and get the RDP browser and also can connect on Android phone using Mobile Connect Android.

It's just the NetExtender that I can't seem to get rolling - any suggestions?

    I forgot to mention I'm using a TZ460 with updated firmware

    Hi @JohnCureton

    Thats odd that you can reach the virtual office page from the same device but getting server may be down on NX.

    Can you run a packet capture on the firewall with the source being your public ip to see if the firewall is receiving packets and if there is any drops?

    Thanks for the reply. I ended up installing NetExtender on a completely different laptop and the connection worked fine. So the TZ470 settings were good but something on the initial laptop is blocking the connection.

    Hey John,

    No worries! possible something blocking incoming or outgoing packets on that pc regarding the ssl ports? Either way, glad you narrowed it down.
