Aug 21, 2020Error connecting to virtual server (HTTP header count exceeded)
I have a new pre-prod HTTPS virtual server. One server in the pool, passing health checks, and the virtual server has zero iRules associated to it.
When I run a curl request to the virtual server, the LTM log is returning errors.
curl --location --request GET 'https://10.10.10.10:443' \
--header 'Host: app.example.com'
curl: (56) LibreSSL SSL_read: SSL_ERROR_SYSCALL, errno 54
I get a successful response from the F5 to the back-end server.
Running version 13.1.3.4.

You might get more relevant views in the iControl forum (Click here). But yes, you can poll the pool members directly using SNMP or any other protocol and then modify the LTM pool configuration to specify a new weight for the pool members. - Javier_Checa_41

Sorry for the misunderstanding, Javier. If you want to modify how LTM processes traffic to the pool, you'd need either use a dynamic load balancing algorithm or modify the configuration. Dynamic load balancing can be done using a plugin or SNMP monitoring of the pool members. Else if neither of these options work for your scenario, you could modify the configuration manually using the GUI or programmatically via iControl.
