curl: SSL read: errno -5961

Hello, we are seeing some strange issues when trying to download from an F5 VIP. Internal the vip sends the requests to Artifactory. The issue is on and off and the SSL setup is only on the F5 side. Does anybody know what this curl error means 'SSL read: errno -5961'?

 

I would just like to know if its the F5 or our internal application.

    If you run curl with the flag "-Sv", you may get some more details of the error.

    ok there could be some possibilities of curl err number 5961 1. incorrect MTU size - check the MTU on both sides 2. ssl protocol is not supported by the cipher that you have add to the vs
