Using SSL/HTTPS on self-hosted instance

[bergamo]

Hi there.

I’m using a SSL certificate, it works at Postman AND SH Console, but not at the n8n. It returned this:

{
“errorMessage": “error:0480006C:PEM routines::no start line”,
“errorDetails”: {
“rawErrorMessage”: [
“error:0480006C:PEM routines::no start line”
],
“httpCode”: “ERR_OSSL_PEM_NO_START_LINE”
},
“n8nDetails”: {
“nodeName”: “HTTP Request”,
“nodeType”: “n8n-nodes-base.httpRequest”,
“nodeVersion”: 4.2,
“itemIndex”: 0,
“time”: “11/02/2025, 11:56:15”,
“n8nVersion”: “1.76.3 (Self Hosted)”,
“binaryDataMode”: “default”,
“stackTrace”: [
“NodeApiError: error:0480006C:PEM routines::no start line”,

]
}
}
