Connections constantly dropping after upgrade to 2019.1.7.0

  • Create an Issue
  • Cancel


Hi there,

I've been a long time user of RDM and I upgraded today to version 2019.1.7.0 (64-bit) and since the upgrade, I am getting constant disconnections. Connections drop then reconnect very quickly. I thought it was my network so setup some network monitoring, and I do not see a correlation between RDM randomly dropping connections and my network activity.

The following is from the RDM application log:

Hi,

The application logs shows us that the external RDP process has terminated unexpectedly. It's hard to infer the reason from this alone. What version of RDM were you using before updating?

Could you provide the session logs of one of the session on which you reproduce the issue? You can enable the session logs through the Help -> Session Logs window. Once this is done, just run an RDP session and reproduce the error. You can then go back to the Session Logs window and send me the session logs of the corresponding session by selecting it in the list and clicking Share (in the titlebar) -> Mail. Just send it to me directly: xfortin@devolutions.net

Best regards,

Having the same issue... connection only lasts about 10-15 seconds, then drops.

Here's the portion of the session log where the connection is dropped:

Hi Scott,

Could you send me the entire log (as described in my previous post)? We can see the "BIO_read returned a system error 60: Operation timed out", but we only this, I have no clue as to what is timing out.

Best regards,
