Server Connection Lost Concern in application

Support
#1

Hi,

Jmix 1.5

Most of the times application throws server connection lost when we access any module either it throw server connection lost error on clicking immediately or in 5 to 10 min range, how to debug.
Any specific reason why this happens, because this restrict user to do any work further in the application.
Since there is connectivity in the application with database

Hi,

Is it basically the same issue - Server connection lost in some seconds?

  • Does it reproduce only on specific environment?
  • Did you try to update Jmix to the latest 1.x?
  • Was there any software\hardware update before this issue start occurring?

Regards,
Ivan

@i.gavrilov This is coming in production and creating a lot of noise from the clien’s end. We would request you to have a look at this urgently and provide a solution iff possible. Otherwise, please let us know what are the scenarios or possible causes due to which this could happen & how can we debug this problem to understand the root cause.

Thanks and hoping a quick response in this matter.

Hi,
Unfortunately we cannot reproduce it or define a cause with current info.
If it’s reproduced on specific environment only then features of that environment might be the cause - network, proxy, configuration, etc.

Can you provide any info about differences between environments with and without this issue? Together with differences in project configurations (if any).

Also if you are able to provide a demo project with that issue and scenario of issue reproduction - it would be useful.

Regards,
Ivan
