APM: Portal Access to SSL Sites

Hello,

 

we've got a VS with a Access Policy showing a webtop with some links like rdp-connections and a Portal Accesss to an internal http Site. Everything's working fine. Now I need a link to a Portal Access to a internal Sharepoint 2016 Site which is only reachable via https, and I only get the error: "Error: secure connection failed The connection to the Server was reset..." (translated from German)

 

a tcpdump shows a Reset from the Server (=another LTM in the LAN) with: Cause: TCP Reset from Server

 

a "curl -vk server" shows cert and everything else

 

every non-ssl-Site is working

 

Version is 13.1.0.8

 

I've tried a lot with SSL-Server-Profile, but no success.

 

any Idea, where to look?

  • Hello,

     

    To find the root-cause the first thing to do is to understand why a TCP RST is sent by the server.

     

    Some checks to do :

     

    • Who send the RST: application server or reverse-proxy F5 ?
    • Does the TCP handshake is ok?
    • Does the SSL handshake is ok?
    • Is there a security brick in place on application side, like anti-DDOS or L7 ACL ?

    Also, FYI, to implement SharePoint SSO with APM there is an iRule to add. You can find it there: https://devcentral.f5.com/codeshare/apm-sharepoint-authentication-v2-draft-1049

     

    Hope that helps.

     

  • Hello,

     

    Can you confirm that you set hostname instead ip in portal access (Application URI)?

     

    Additional the request is done by floating and not self (the rules are open from floating?)

     

    Regards
