I install collabora online docker on my server.
I follow instructions from

The only difference with this standard installation is that I use ispconfig.
I defined and I add all the proxy parameters in my options page
I use SSL with Let’s Encrypt

I can’t open any file with the error in nextcloud.log :
“cURL error 35: error:04067084:rsa routines:RSA_EAY_PUBLIC_DECRYPT:data too large for modulus”

It seems that there is a problem with certificates, but I don’t know where and I don’t know what to do. Can you help me ?
