Nope, I'm not joking.
You asked for help but didn't give any information. When asked why you thought it was docker related and to point to the docker you suspected you showed a list of 10 or more dockers with no information and no direction of what one you suspected and why. When asked what you have open to the internet you said only port 80 and no explanation about how it is configured, where is it forwarded to/what are you accessing through it, etc.
When asking for help, releasing pertinent information is needed. If the problem is related to internet things (security, getting hacked, dns errors, etc.) releasing the basic information about how you are configured initially will help people spot problems quicker because they won't have to ask for the basic information so they can decide what direction the questions need to go in.
Asking for help with no information will slow down the process. Something that could be spotted and fixed in a day can now take several days, all the while, the security hole that may have been used to hack into your system is still open all because that basic information is not being released.
