500 Internal Server Error - CAPTIVE PORTAL

[FabioGarcia]

Dears,

PA220 with interfaces as per below

ethernet1/4 19 1 Local-Network vr:RT-LAN 0 172.26.57.1/25
ethernet1/5 20 1 Local-Network vr:RT-LAN 0 172.26.57.129/26
ethernet1/7.105 269 1 Local-Network vr:RT-LAN 105 172.26.59.1/27
ethernet1/7.106 270 1 Local-Network vr:RT-LAN 106 172.26.59.97/27

Captive portal already configured and we double checked everything... All looks good.

PA220, PanOS 8.0.8

All tries to access Captive Portal shows up error message: 500 Internal Server Error

- We tried to access all IPs with mgnt profile "response pages"

- Redirect is OK, but users face that error message

- Already tried restart web-server process and mgnt server process

- This has nothing to do with HTTPS Certificate distribution, that is just a test forcing Caotive portal to show up (works on any other box we have)

Test #1 ip 172.26.57.1 port 6082

Test #2 ip 172.26.57.129 port 6082

Test #3 ip 172.26.59.1 port 6082

Test #4 ip 172.26.59.97 port 6082

Hello,

If your captive portal is n the PAN itself, you might want to call TechSupport as this could be a larger issue.

Hi @FabioGarcia,

Can you also try to restart the User-ID process? This has fixed this issue for us in the past. Otherwise, log a TAC case like @OtakarKlier has said.

Thanks,

Luke.

I found the problem

The Captive Portal URL was modified in Version 8.X

Captive portal URL PANOS v7.x

https://X.X.X.X:6082/php/uid.php?vsys=1&url=http://www.URL.com

Captive portal URL PANOS v8.x

https://X.X.X.X:6082/php/uid.php?vsys=1&rule=&url=http://www.URL.com

This Solution was helpful.

We moved from 7.1.14 to 8.1.12

We modified our Captive URL like, 

https://example.com:6082/php/uid.php?vsys=1

to

https://example.com:6082/php/uid.php?vsys=1rule=&

Thank you,
