I upgrade pmm1 to pmm2 on Docker . When I configure pmm-client ,I meet some errors.

It seems a question of SSL cert. How can I solve this question ? Thanks

Might be something wrong with ca certificate.  
Can you verify your SSL certificates, also for a test try creating a new one and test.

Did the same certificates work back in PMM1? normally a server certificate needs an [alt\_names] section with all IP addresses and DNS names associated.  
Also `pmm-admin config` calls `pmm-agent setup` under the hood so you shouldn’t need to run that directly. Simply start the pmm-agent service and run `pmm-admin` config.
