Hello, if, but is only a supposition, if this error occurs on Cloud Hosted, i may have the same error when try to open FO.

If true, try to Rotate Secretes on Maintain section of VM on LCS.

Than rotate SSL certificates.

But, if not, give us more details about your environment.

Hi,

What type of environment are you using? Is the error coming before or after providing your credentials?

Hello,

Try to open the workflow from Microsoft Edge.

The workflow editor doesn't support other browser. I've a similar error but in french :-)

Thank you,

Giorgio

Hi @CU15021230-0,

I agree with Giorgio’s recommendation. Please try opening the workflow designer in Microsoft Edge.

If you find this answer helpful, please consider verifying the answer. 👍

Hi Community member,
I often faced similar issue, to resolve workflow opening issue you can try below as suggested. (It works for me).

Click Window +R

Input "CMD" under Run box.

Paste the following command: rundll32 dfshim CleanOnlineAppCache

Click Enter.

Try to reopen the workflow in Edge.

Please note, if you have already opened the workflow in the system for any other client. you have to close the privious one.

Hello,

I've another suggestion: can you try to update Edge, then open the workflow with privacy mode and enable all the options asked from the borwser's pop-up?

Thank you,

Giorgio
