My apache2 web site was working but now is sending me to the original host account it created instead of the wordpress host I created

I have been working out problem after problem on digitalocean for weeks. the documentation is poor and the structure of it is even worse. I am using ubuntu 20.4 with apache 2 and php 7.4 as required by wordpress and I have separated the mysql server from the apache2 wordpress server they are on seperate droplets. I have connected them with the firewall and connectivity is good. that is when I installed wordpress and ran the install from the site tapropar.com. it all seemed to be working correctly. but, gutenburg was not saving pages or posts. I installed the original editor and tested it. it saved the page. Then I completed the multisite install for wordpress. it looked OK but it would not save new users or new sites. I found another document specifically for multisite on ubuntu and made the changes that it suggested. now I can’t access the site at all. all I get is the empty original host account. I am not happy and I don’t know where to turn. any assistance would be helpful right now. ssh was installed but doesn’t work either. and I have done everything that the documents require. this has been the issue with every step along the way. I just want to get my system up and running and then I can run updates when needed and can take care of business. the original install couldn’t even be updated because my tech had origianlly set the system up on ubuntu 18.04 and ubuntu 19 has been dropped. thats just crazy because I never recieved any notification or anything. is that how things work here? please advise.
