HTTPS monitoring failing

Dear All,

 

We are facing issue with HTTPS monitoring.

 

F5 load balancing and monitoring some of the server on which SSL is disable (last week) and only TLS 1_2 version is enable.

 

Since SSL is disable on server, F5 monitoring is failing.

 

Request you to please let me know, how to create a HTTPS monitoring parameter for monitoring TLS1_2 version enabled server.

 

Regards, Anil

  • You will need to configure the Cipher List in the monitor properties.

     

    See this DevCentral thread: Ciphers

     

  • Hi, if you need an SNI connection, maybe you need an external monitor

     

  • Hi Anil, I agree with Cjunior comments. Please enable external Monitor to your pool member.

     

    Or configure below cipher. Go to Profile--> SSL--> ClientSSL--> click on SSL profile--> chiper(paste below & try) !SSLv2:!EXPORT:!DH:RSA+RC4:RSA+AES:RSA+DES:RSA+3DES:ECDHE+AES:ECDHE+3DES:@STRENGTH

     

    Hope it will work for you. Please let me know if any question

      can you please tell me how it will work without applying this profile to monitoring?... how to assign the created SSL profile to HTTPS monitoring??
  • what version are you using? health monitor supports tls1.2 in 11.5.

      Hi Nitass, you state that health monitors supports tls 1.2 in 11.5 does this imply that tls 1.2 is not supported in 11.4?

  • Hi Nitass,

     

    it is not working. I followed your post and configured F5 monitor. but still it is failing..

     

    please let me know the alternate way to solve the issue.
