Nextgen gallery not working on new server, how to fix?

Question

WordPress

Good afternoon/evening.
I made my site on wordpress (I bought a VDS for 4 bucks without a domain. Let's say 5.34.183.136), I installed the nextgen gallery plugin in order to embed beautiful slide shows, etc., etc. I recently bought a domain and attached it to the host, everything went well. The domain is working, now you can go to the site by domain name and not by ip. Yesterday I was forced to move to a new server. made a database dam, made a backup of the wp-content folder. uploaded everything on the new server, unpacked the database, uploaded everything, except nextgen gallery!!!! for reasons unknown to me, it constantly requests pictures from the old ip address. what should I do?
found with grief that nextgen gallery stores all its links in encrypted form (base64) in the database. I found these links, changed them to my domain (or a new server IP), as soon as I go to the site, I select the post where the nextgen gallery slider is located, as it immediately replaces the name of my domain or server IP in the database with the old address 5.34.183.136. Mystic, I don't know what to do next. I can't refuse nextgen gallery, as there are 581 posts on the site, each has a slide show! help what can i do?

When moving, forget about manual transfers. Modern WordPress is transferred in a semi-automatic mode. For example, like this:
https://ru.wordpress.org/plugins/duplicator/
Next, I copy my answer to the 10th similar question on moving in the last 2 weeks:
Go to the plugin, click "Create package". Next, next, next.
We get installer.php and archive. We upload them to a new hosting. Run site.com/installer.php. Enter a new username and password for the database.
Next, next, next.
At the end, follow the instructions on the screen - log in to the vp, resave the permalinks. Delete the installer files and the archive.
Everything. Everything has been moved.
