CRM-Extension – SSL-Certificate not found

[Anonymous]

Hello, 

i'm trying to build an app integration with a custom card. 

I built the app with python and hosted it on my cloud server.

Obtained a let's encrypt certificate to secure the connection to my server. 

Unfortunately, i always get an "SSL-Certificate not found" error in the monitoring tab of my app and the card is only showing an error message.

I don't understand what causes this error, because the certificate is working perfectly in the browser. 

I'm new to HubSpot, this is the first app i write, and i don't know where this error comes from. 

May anyone can provide a solution or point me in the right direction to what i'm missing?

Hello, 

thank you for the reply. 

Unfortunately this thread doesn't help me. 

I have a valid certificate and the server is running on port 443 (not localhost), but i still get this error message.
