Error is 99: Cannot assign requested address

[mgibbons]

Hello,

I’m trying to access a remote NoMachine server from an android tablet.

Host is on NAT and local connections work normally. External connections from host client to other NoMachine hosts works normally also.

Host NoMachine: nomachine-enterprise-desktop_6.9.2_1_amd64.deb Ubuntu 18.04.3

Client host  NoMachine Server shows to connect to nx://72.130.27.203:26300 and GW port 26312

On the host –upnpstatus and ifconfig -a shows:

Local IP                   192.168.5.158
Gateway IP                 192.168.5.1
External IP                72.130.27.203
NX port 4000 mapped to:    72.130.27.203:26300

My router shows 192.168.5.158 26300 > 4000 TCP and UDP

My android log shows

3556 3767 10:14:58 448.706 ClientSession: Going to start session ‘/sdcard/NoMachine/Connection to 72.130.27.203.nxs’.

Please advise how to resolve.

Thank you

Hi. I suppose you’ve created a new connection and used 72.130.27.203:26300 in the hostname field. You can set the correct hostname by selecting the connection in the list and tapping Edit, then setting 72.130.27.203 as hostname and 26300 as port. Please let me know if this helps or, in the contrary case, tell me how you configure the connection so we can detect possible issues.

Yes, that was the problem. When I did as you suggest  it worked correctly. I think the NoMachine server prompts are somewhat misleading.

Thank you.
