The requested parent profile (clientssl) was not found

Hello,

 

may be this link can help you link. It describes the same kind of issue.

 

It rather looks like a typical v11.5,v11.6 BS with certificates/keys going missing from SSL profiles after the upgrade.

Try the following:

Go to

Local Traffic -> Profiles -> Clientssl

-> Open the

clientssl

default profile

Include the

default.crt

certificate and

default.key

private key in the chain, click update.

Reset device trust, and build a new sync/failover group.
