Traccar does not display server access panel.

Hello.
Server on AWS with Ubuntu server 20.04 and mysql

When entering by web / app does not go beyond the circle rotating

Down here part of the log and as I have confirmed my traccar xml

hi, i dont think it can reach DB

try changing this line

<entry key='database.url'>jdbc:mysql://127.0.0.1:3306/traccarDB?allowPublicKeyRetrieval=true&amp;useSSL=false&amp;serverTimezone=UTC&amp;useSSL=false&amp;allowMultiQueries=true&amp;autoReconnect=true&amp;useUnicode=yes&amp;characterEncoding=UTF-8&amp;sessionVariables=sql_mode=''</entry>

into this one

<entry key='database.url'>jdbc:mysql://localhost/traccarDB?serverTimezone=UTC&amp;useSSL=false&amp;allowMultiQueries=true&amp;autoReconnect=true&amp;useUnicode=yes&amp;characterEncoding=UTF-8&amp;sessionVariables=sql_mode=''</entry>

Adrian thank you for your prompt response.

I'll try to change that line.

Otherwise I attach my tracker-server.log by this means.

https://transfer.sh/C37d/tracker-server.log

seems ok to me, i remember having the same problem, my server is up and running for some time now, 3y maybe, and i cant remember how i fixed that, also on a vps at Hetzner

i also documented every step, ill try to find the doc and submit my steps
