What does this mean? Just tried opening tonight's host to see if all works well, and I've just got this? I didn't have this problem last night....I've also tried starting a new sim as a host, & also get the same message. The Welsh contingent. Aron, or Ar to mates. Also known as 88E or ThatManCalledAr.

It means the simulation can’t open the port you’ve selected successfully. Either you’ve got a simulation open on that port, or something else is using the port. A reboot usually fixes it.

A system reboot or a router reboot? Just started getting this today for some randomless reason. Reboot the system being the answer.

A reboot of the computer shouldn't be required, but is an easy way of ensuring other applications are closed. Rebooting router won't help. Basically SimSig asks Windows "can I have port 50505 please" and Windows [computer] says "No". Usually it's because a program is already using it. I doubt in the above cases, but it could also be blocked by a firewall rule or antivirus. SimSig Boss Log in to reply |

Cheers Geoff. No idea what was going on, but nothing else was using the specific ports at the time. I had checked "netstat -a" through Command Prompt and resource monitor, and hadn't changed anything router related from the day before. Doesn't seem to be an issue today, all port ranges that I've set up in Port Forwarding for SimSig use are open when pinged. Think I'll blame Norton. It's always Nortons fault. Craig.

Unless SO_REUSEADDR is set, this can also happen if some program was recently, but isn’t any more, listening on that port, and one of the connections to said prior program didn’t shut down cleanly. In that case the port will be locked up for some period of time to prevent in-flight or retransmitted packets intended for the old program from being confused with packets belonging to connections to the new program, I believe.
