Hello @Vadim_Yalovets Also, we tried to change the password for the admin user successfully. During the PMM configuration, we didn’t get any errors. But still, we were facing the same issue as we mentioned in the screenshot above. ---

Hi, from what I see in the logs - in particular, `3306: connect: connection refused` error - it seems like PMM Server is trying to connect to a MySQL database, which we don’t support for PMM Server persistence. ---

Hi @ademidoff Thanks for the reply the version that you are pointing to here is MySQL or PMM? Currently, we are using: **MySQL version - 8.0.34** **PMM server version - 2.42.0** **OS VERSION -“24.04 LTS (Noble Numbat)”** Do we need to configure any other specific version of PMM kindly let us know. **Note:** We also tried to install the older version of **PMM 2.38.0** still facing the same issues. For every time we tried to resolve this issue at last we came up with the error invalid user and password. ---

@ademidoff I am also facing the same invalid password issue while resetting PWD for admin user, tried all above mentioned options, still same issue. The login is working fine for other non-admin users, how to reset the admin PWD OR create a new admin user!! Do we have any solution here? Tried ones: ````auto docker exec pmm-server change-admin-password admin@123 docker restart xxxxx``` docker exec -it pmm-server bash grafana-cli --homepath /usr/share/grafana admin reset-admin-password admin@123 supervisorctl restart grafana``` ```` ---

Hey! I’ve just tested it one more time on `percona/pmm-server:2.44.0` and it worked fine. I used the same password “admin@123”. However, if your password contains special characters, like “!/$&%#?\*”, you should wrap it in double quotes. So the syntax is as follows: `docker exec -it pmm-server change-admin-password "admin@123"`. Upon completion you should see the message “Admin password changed successfully ✔” in the console. There is actually no need to restart grafana, it works without restarting. Depending on PMM version, the command syntax may vary. You can refer to [FAQ - Percona Monitoring and Management](https://docs.percona.com/percona-monitoring-and-management/2/faq.html#how-to-change-the-pmm-password-for-a-default-admin-user). Please let us know if it helped. Alex ---

@ademidoff Our PMM version is 2.39.0. As mentioned in the doc, I had tried and also got success response, but still its showing invalid username OR pwd!! `“Admin password changed successfully :heavy_check_mark:” ` Also, our PWD is not having any special character, it’s a plain text. As admin user was being used for pushing metrics, its failing for all clusters now. Any alternative here to login using admin user and also to push metrics???

Hi! Sorry to hear it didn’t work for you ☹ We tested 2.39.0 as well and didn’t see what could be wrong with the password reset. Well, one option to reset the admin user’s password is if you have at least one more admin user. If that’s the case, you can log in to PMM, go to [https://pmm-server/graph/admin/users](https://pmm-server/graph/admin/users), select the admin user whose password you need to change, and change it via the user interface. Otherwise, what is the output of `docker exec -it pmm-server change-admin-password ...`? Alex ---

had this problem too. I solved it by stopping every PMM client, then resetting the password and waiting a few hours. I’m not sure, but I guess that the client tried to log in with an incorrect password, and Grafana/PMM blocked every login attempt even when the password was correct. After a few minutes / hours it worked again, then I updated the pmm-client config with the new password and restarted the clients.
