I installed Percona PMM with Docker and it’s up and running on the PMM server: ```auto root@cop:~# docker psCONTAINER ID        IMAGE                  COMMAND                CREATED             STATUS                       PORTS                                         NAMES 6459173799da        percona/pmm-server:2   "/opt/entrypoint.sh"   About an hour ago   Up About an hour (healthy)   0.0.0.0:8080->80/tcp, 0.0.0.0:8043->443/tcp   pmm-server ``` I configured Nginx as reverse proxy with SSL and a trusted SSL certificate and I can correctly access to Grafana if I access to [https://pmm.my.domain.I](https://pmm.my.domain.I) installed PMM Client on a MySQL machine, I configured it to connect to the PMM Server but I receive some connection timeouts and I cannot understand why. My PMM Client version is: ```auto root@mysql3-staging:~# pmm-admin --version ProjectName: pmm-admin Version: 2.9.0 PMMVersion: 2.9.0 Timestamp: 2020-07-14 10:11:43 (UTC) FullCommit: cae4d06914b68bb625e9ff7dcd2d7baf3cac9227 ``` I configured PMM Client to connect to [https://pmm.my.domain:443](https://pmm.my.domain:443): ```auto root@mysql3-staging:~# pmm-admin config --force --server-url=https://admin:password@pmm.my.domain:443 Checking local pmm-agent status... pmm-agent is running.

Checking local pmm-agent status... pmm-agent is running. ``` PMM Client is running: ```auto root@mysql3-staging:~# ps ax|grep pmm 22986 ? Ssl 0:00 /usr/sbin/pmm-agent --config-file=/usr/local/percona/pmm2/config/pmm-agent.yaml ``` But I cannot add a new MySQL source: ```auto root@mysql3-staging:~# pmm-admin add mysql --query-source=slowlog --username=pmm --password=password Failed to get PMM Server parameters from local pmm-agent: pmm-agent is running, but not set up. Please run `pmm-admin config` with --server-url flag. ``` I then checked that PMM Client cannot connect to PMM Server: ```auto Jul 31 10:02:24 mysql3-staging systemd[1]: Started pmm-agent.

Terribly sorry we missed this and no one has responded yet…I looked over your steps and they seem to all be correct.  Can you run ‘pmm-admin status’ and post the output.  Just curious if all connections to PMM Server are impacted or just for the registration action.  Also, instead of FQDN, can you try adding MySQL monitoring by IP address to see if that works (might isolate where in the code we’d need to look if it’s a bug).  And just to be complete…I see you’re running client 2.9.0 is that the container version as well “docker exec -it pmm-server curl -u admin:admin [http://localhost/v1/version](http://localhost/v1/version)”.
