I have CrazyMax's "WindowsSpyBlocker" installed on my laptop's Windows 11 with all three firewall options applied at all times:
1 - Add spy rules (recommended)
2 - Add update rules
3 - Add extra rules (ONLY use if you know what you do)
When I visited "uscis.gov" and attempted but failed to submit a form. I tried again a few times but didn't get any results until this little app came to my mind.
I opened WindowsSpyBlocker and chose option #4:
4 - Remove "WindowsSpyBlocker rules"
Bingo!
Just try applying option 1,2, and 3, then go visit some .gov sites for forms...
