Problems connecting to Azure Devops

ZEBIT — Mon, 08 Jun 2020 06:45:03 GMT

Hi,

We use a PA3260 with PanOS 9.0.7.

Since 2 months our programmers have problems connection to Azure Devops. The always lose the connection several times a day.

When they work from home there is no problem, so I think the problem is the firewall. I already searched in the monitoring for deny's or SSL decryption errors but can't find anything. After two three days of searching and programmers that are complaining I don't know what todo. So maybe somebody of you are having the same issues and a solution?

Hi @ZEBIT ,

Anything in the threat logs ?

Create a filter and check the global counters for eventual drops.

Cheers,

Hi @kiwi

That is indeed the problem. How can I fix?

Hi @ZEBIT ,

In case of a false positive then I'd enable the PCAP in the vulnerability profile so you can download it from the logs and to have it analyzed by TAC in case the signature needs a fix.

In the meantime you can add a workaround by adding an exception in your vulnerability protection profile.

Cheers,

Hi @kiwi

I made a work around and will analyze this with TAC.

Hi @ZEBIT ,

You enable the packet capture in the actual Vulnerability Profile :

Trigger the threat again and you should be able to download the PCAP from the threat log.

Hope this helps !
