Stuck in ArcGIS Sign In loop

[TylerT]

Greetings,

I have a project aprx that is signed into an Enterprise portal that times out regularly.  Upon opening the project I get the sign-in dialogue followed by an internet browser opening to the Enterprise Portal.  The Enterprise Portal login in successful and an OAuth2 Approval code is generated.  I copy/paste the code back into ArcGIS Pro but the submit button stays grayed out.  Closing the sign-in dialogue does not continue to open the project, rather another ArcGIS sign-in dialogue pops up, and I'm stuck in a loop unable to open the project at all.  Any ideas?

Thank you,

Tyler

Tyler - give this workflow a go to escape the sign-in loop:

1. Go to Start > search for Regedit
2. Navigate to HKEY_CURRENT_USER > SOFTWARE.
3. Find ESRI folder and rename it to ESRI_OLD to reset the registries.
4. Relaunch ArcGIS Pro, and sign in.

From previous support cases, this seems to fix the issue.
