Hi @Bilalayub,

So sorry to hear that your workflow got interrupted by that :frowning:

I hope to be able to help, but only if you have ssh access to your VM where you run PMM Server. Pls let me know if you have, I’ll drop you the steps which hopefully can get it going.

Hi! Apologies for the delay with the answer :frowning: )

So, given that PMM Server gets stuck at the point when it tries to update the dashboards, here are the steps to perform:

1/ Make sure you make a snapshot of your AMI VM to a safe place from where you can restore it if anything goes wrong.

2/ cd to the following directory:

cd /usr/share/percona-dashboards

3/ locate the file and replace it with content from the repo:

4/ then restart all processes via supervisor:

supervisorctl restart all

Hope this will get you going, please let us know otherwise.
