Devolutions Client: Internal Server Error

Hello John,
I have assigned your thread and someone from the support will contact you.

Regards

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

Best regards,

Erica,

Thank you. That fixed it for us.

Scratch that... it fixed the 500 error, but still unable to log in.

Hi Sam,

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

Regards

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.

Regards,

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.

Regards,

Hi Sébastien,

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

Thanks and look forward to the resolution.
