Captive portal fails randomly

Hi, we are having some issues in captive portal authentication.

Users get this message randomly (with the correct password):

Once this message appears, it's impossible to log in. The user has to close the navigator's tag and try again until it works.

These are the related pdpd.elg log entries:

[16716 4105733904]@hades1[29 Oct 16:00:00] [TRACKER]: #405402 -> INCOMING -> PORTAL_REQUEST -> Portal Hello from ip: 10.10.4.22

(The user gets here the "login failed" message)

(After a few clicks in the "log In" button, the user close the tag and reopen it)

(Log In Success at first attempt)

Any idea or clue about this issue? This is a R80.10 on-premise gateway.

Thank you!

Alex

May need a TAC case to troubleshoot what's going on here.
Is this consistent across browsers, or with a specific browser?

It happens with several browsers.
I have opened a case recently, I will update this post in case of any relevant data.
Thank you!

I have the same issue. Did TAc solve the problem.

If I remember correctly, the problem was an AD that was not responding.
The solution was to recover the AD but we could not clarify why the gateway was stuck making requests to the same unresponsive AD instead of trying with the rest of the list.
