Guest portal issues after patch update.

[alessandrodematos1]

Hello everyone,

I have a Cisco ISE version 3.3 and I use the guest portal to authenticate my guest users.

What happened is that after an update to patch 7, a strange behavior started.

What happens is that the guest portal stops responding (connection timeout) and only starts working again after restarting the services.

The strangest thing is that the sponsor portal continues to work and access to management also continues to work.

We have already collected logs, but we were unable to identify the problem with Cisco support.

Have you ever experienced anything similar?

Hi @alessandrodematos1 ,

 you have an ISE 3.2 and not ISE 3.3, correct ?

 What was your Patch before the update to Patch 7 ?

Best regards.

Yes, it's correct, my bad.

Patch 3

Hi @alessandrodematos1 ,

 bug I faced:

• CSCwi74567 Corruption in ISE Portal caused by inconsistencies in the DB

use the following CLI command to check for errors:

ise/admin# show logging application guest.log | include "Software Error"

You said " ... We have already collected logs, but we were unable to identify the problem with Cisco support ... ",

• How many Nodes do you have ?
• What is the result of the following command ?

ise/admin# show version history

Regards.

Notei que você também fala português hehe.

Só para ficar ciente, fizemos o rollback para o patch 3, mas não resolveu, então parece que algo no patch 7 gerou algum tipo de crash que não foi resolvido nem com o rollback.

Olá @alessandrodematos1 ,

 no rollback você utilizou o comando abaixo, correto ?

ise/admin# patch remove 7

Hi Alessandro,

We experienced a similar issue after applying some other patches on version 3.2, but p7 was fine. Portal gets stuck loading at different steps of the login/registration. The same also occurred randomly sometimes with no previous patch installation, usually after making changes to the customization. Our portal has intense javascript customization, but we can't tell if it's related to that.

What we did is make a slight change to the customization, and save again. Sometimes it helped immediately, sometimes not. But after max 1 day it always worked again. Not sure if the saving did anything at all.

Last time that it happened, the users suddenly got served a version of the guest portal that was 1 year old. It's surprising that such an old config is still present anywhere... So my current guess is that there's something wrong with the web server, maybe it sometimes fails to grasp the config, or a sync issue between nodes.

It's hard to capture the symptoms as well as the fix, so if anyone faces similar issues, please report. Thank you!
