Any attempt to access kp.org/kaiserpermanente.org receives:

Bad Request
Your browser sent a request that this server could not understand.
Size of a request header field exceeds server limit.

Access successful with Chrome and Firefox.

Not using a VPN. Have Adblock, google translate, google docs offline, and megasync extensions installed.

Brave Version( check About Brave):

v1.3.118 (just installed today) Same failure on whatever the prior release was. I think the failure started with that release, not sure.

@len5742,
I’m seeing a ERR_TOO_MANY_REDIRECTS message when I attempt to visit the site in any browser (tested with Chrome, FF and Vivaldi browsers). Can you confirm for me that that is the proper URL?

[len5742]

What url are you entering?

kp.org is the website.

kaiserpermanente.org is another name for the same website.

That’s what the slash in the middle was trying to communicate, perhaps a bad choice. Are you entering kp.org/kaiserpermanente.org?

But even if I enter that, I get the same error message I reported. Nothing about too many redirects.

On windows 10 (not sure if it actually matters), but both sites loaded fine. I would clear the cookies/cache and then re-start the browser maybe? (test with/without a vpn?)

[len5742]

Clearing browser data fixed this.

I would note that after I clicked to initiate browser data clearing, the screen locked and never returned control. Happened twice. But whatever, the escape key worked.
