TS agent SSL error

L1 Bithead



I've been trying to add a new TS agent on my firewalls. As there is no redistribution for user-{ip+port} mapping, I want to map the TS agent to 2 FWs. Backend FW is connected correctly, Frontend FW is in error.

I can capture the following between FW and TS agent :

- FW to TS : SYN

- TS to FW : SYN/ACK 

- FW to TS : ACK

- FW to TS : RST


I've got the following error:

show user ts-agent state

not-conn:idle(Error: Failed to Connect to, SSL error: error:00000000:lib(0):func(0):reason(0)(5) )


Also on TS agent side I've got the following error:

05/04/22 12:33:57[Info 1571]: Client thread 2 with IP is started.
05/04/22 12:33:57[Error 1946]: SSL 2 accept error: 5-10054!
05/04/22 12:33:57[Info 1659]: Connection closed.


The thing is that there is no certificate configured for any user ID agent.

I tried to restart user-id process on the FW with no success.


Does someone have an idea ?

Thank you for the post @MMerlier


is there any URL Filtering / SSL inspection between Firewall and TS Agent? There might be an issue similar what is described in this KB: https://knowledgebase.paloaltonetworks.com/KCSArticleDetail?id=kA10g000000ClKSCA0


Kind Regards

Hi Pavel,

We are not using a SSL decryption at all, and we use URL filtering but a very specific rules that are not about traffic from FW to terminal server.

Also we are using default service routing (so using management interface)

Did you ever get to the root cause of this? I am having the same issue which just started today and no recent changes. Getting the same error with firewalls sending their user id data to panorama.
