HTML 500 error when trying to signup

[ProfessorVarox]

I recently installed Kutt on my server and everything worked fine but when I tried to signup I get the message An error occurred

Chrome Developer Console output:
Failed to load resource: the server responded with a status of 500 () api/v2/auth/signup:1
Sometimes I also get this error in Chrome Console:
POST https://url.infinity-systems.eu/api/v2/auth/signup 500 _next/static/chunks/2b26bdeb7491974facd25746912241b815a721eb.b9ac63e96ca9aab19faa.js

When I try to reach api/v2/auth/signup I get the following error:

npm run build Output:

I needed to resubmit because @poeti8 closed #415 without waiting for my response if his solution worked. The mail credentials are correct, I verified them three times

@ProfessorVarox did you find any solution? I am getting the same error!

[ProfessorVarox]

No, I'm sorry. I tried it a fews days ago on another server but the same error

[ProfessorVarox]

I tried using docker today but the same problem

[SplatDev]

Same issue here. Just set it up via docker compose and everything is correct as far as I see.

[wissamataleh]

I faced the same issue when trying to deploy it using docker compose. It was related to SMTP settings, apparently I miss configured it. After setting MAIL_PORT=587 and MAIL_SECURE=false in my environment, everyting worked fine with no related issues.

MAIL_HOST=host.example.com
MAIL_PORT=587
MAIL_USER=user@example.com
MAIL_PASSWORD=password
MAIL_SECURE=false

[vec-tor-void]

Hi @ProfessorVarox , can you also share your nginx config for this? wanted to understand how this is being deployed

[AlexandreBonneau]

Thank you @wissamataleh ; setting MAIL_SECURE=false instead of the default MAIL_SECURE=true saved the day when using the STARTTLS port 587.
