@marcellocello
After inspecting the logs, it looks like you initially used a simpler mailer configuration:

MAILER_USE_CUSTOM_CONFIGS=false
(As indicated by the backend server log: "Using simple mailer configuration")

Later on, it seems you updated your .env file. However, since our backend is designed to retain previous configurations, this is likely causing the error.
If you can provide us with the previously used MAILER_SMTP_URL, we can try to reproduce the issue on our end.

In the meantime, a quick fix would be:

Open the InfraConfig table in the database and delete a row where name = MAILER_SMTP_ENABLE.
Stop and Restart again the Hoppscotch Docker container.

thanks for your response and help. now the application can be run, however, when I click Login an error appears "Unable to load auth providers". I have setup Microsoft Auth in .env file

VITE_ALLOWED_AUTH_PROVIDERS=MICROSOFT
# Microsoft Auth Config
MICROSOFT_CLIENT_ID=***this my microsoft client id***
MICROSOFT_CLIENT_SECRET=***this my microsoft client secret***
MICROSOFT_CALLBACK_URL=http://localhost:3170/v1/auth/microsoft/callback

and this is when I access port 3100

Can you provide the browser's network log?
Also, if any errors occur, please provide the Docker container logs.
