This application has been running for over 20 years.  It is on Metro Nashville's cloud network where, as a contractor, I have no visibility of pretty much anything except the virtual server.  These interruptions began occurring about 3 months ago as pandemic inactivity concluded.  These connection closures are sometimes frequent and sometimes infrequent.  Users find themselves disconnected in the middle of an operational function.  They are using Dynamic Connect for telnet.  Has anyone experienced this and found the problem.  Are there any server or workstation firewall or antivirus settings that could have been recently changed by Metro's IT department that could cause this?  Also can anyone recommend an ssh server for Windows that could be substituted for telnet?

Just to double check, what is your keep alive time set for? We had to increase this to 300 seconds on our DC telnet sessions.

I suspect that the root cause of problems was _ PC's requiring Windows 10 updates.   At our company here of 40 PC's _ in recent months _ several machines exhibited quirky behavior _ until updates were installed.   Of course _ manually checking for the need for updates on individual PC's is necessary.

We use _ and I very much like _ Dynamic Connect.   A hitch with moving to another terminal emulator is that _ some of the UniBasic code takes advantage of DC functionality _ so that _ there are compatibility concerns.   wIntegrate is certainly worth considering.

As I checked my office laptop I see that the keep alive box was unchecked.  The time is 7200.  I'll have to check with the on site users today and see if that makes the difference.  I'm pretty certain that traffic is the problem, they have a Lutron server on the same cloud that controls lights and perhaps other things.  The Metro IT department controls all Microsoft and other updates; sometimes they tell people sometimes they don't.  I would suspect they are very up-to-date.  IT would like to switch to secure shell, I've used Accuterm and Putty so the Windows server is the only unknown.
