I've noticed issues on our instance of Forms Portal the last day or two.

Forms will either not load at all (I get a generic time out error from one of our network providers), or it will load the form half-way showing the title and favicon but a blank page, or sometimes it will load just fine but slower than expected.  It's very intermittent why it works sometimes and not others, and I haven't been able to pin down why this is happening.

I think I've ruled out that it is a network or ISP error, so I'm thinking it has to be Forms.

Restarting servers did not resolve the issue.

I'm running Forms Portal in a DMZ with the same routing service and database as our internal forms instance.

The internal forms instance is not having this behavior, only the public one in the DMZ.

I can't find any errors or issues anywhere that I look in Forms Portal, but I am seeing these errors on the Event Viewer on the Internal Forms server:

[500]: Sorry, but the page you requested cannot be found. Be sure that you entered the URL correctly, and then refresh your browser.

Function: Error

I'm seeing two of those errors each time I try to load form form through the Portal and it fails, maybe 30 seconds later.

I'm running LFDS 12.0.2503.265, with both instances of Forms on version 11.0.2311.50556, with no changes to any configurations or installations for weeks (nothing to explain this recent change).

Has anyone ever seen something like this before?
