ERR_SSL_PROTOCOL_ERROR error in AIO Nextcloud Ova


Hello to everybody and I’m sorry if my problem is recurrent. But I don’t fins how to solve
I imported a OVA in a Virtualbox in Debian Machine. I could do the initial installation without problems.
When I try to go to my website, I see the next message


My dynamic dns appoint to this ip. I have a dynamic Dns

My router has ports open to my VM

In the first part of initial configuration, when it asks about domain, a filled with “” and considered like valid.
I don’t find where is my problem

Hi, see What can I do when Nextcloud is not reachable via my domain or if I get `SSL_ERROR_INTERNAL_ERROR_ALERT` when opening my Nextcloud domain? · nextcloud/all-in-one · Discussion #2105 · GitHub

Thanks for your answer

Did you follow the steps mentioned in the readme of Index of /aio-vm?

Thanks a lot. But, I think that my problem it’s my ISP. I think port 443 is not allowed. I send a message to ask for it.
I’ll tell you something when I’ll have news.
