Devolutions Client: Internal Server Error

  • Create an Issue
  • Cancel

Hello

Since updating to Devolutions Server 4.0.3.0, I receive an internal server error when browsing to Devolutions Client over the web.
However, connections from Remote Desktop Manager are working well.

Today, I updated to Devolutions Server 4.0.6.0, but I still receive the same error:

I also upgraded this morning from 4.0.3 to 4.0.6 and getting the same error.

With that said...It only appears to me to be affecting the web browser UI. I have been able to connect via the RDM client and the iOS app.

We are investigating. We will be back shortly

Sorry about that

Hello,

Could you please check if the IIS Rewrite Module is installed on your server? On the DVLS Console, click on the Server Diagnostic button.

If it is not installed, you can download the IIS Rewrite Module here https://www.iis.net/downloads/microsoft/url-rewrite

Hi Sam,

Do you have a non-alphanumeric character in your username ?

yes...

domain\username

Hi Sam,

Is it possible to know your username ? We observe that we have some problem with specific character after the "\" symbol.

I PM'd it to you

Thank you, I installed the rewrite module, it's working now.

Hi Sam,

We currently investigate the bug. But temporary, I think you can double the "\" in the username textbox (domain\\username). It seems working for now by this way.

I will inform you when the bug will be fix.

Hi Sébastien,


Yes, the \\ works for me as well for a work-around.


Thanks and look forward to the resolution.
