Maybe try restarting your Minecraft or could be a problem if you have a VPN on. This was a issue for me too but it was because of my VPN. If you have connecting issues please check your internet too.
As mineverse is blacklisted, many people cannot log onto the server. Try using this > https://squidhq.com/. It is something that adds no modifications to minecraft, but it allows you to connect to blacklisted servers. If not, try restarting your computer or simply wait a day, as these two things help a lot of people.
This isn’t random stuff, as it was even recommended by Cypriot. https://www.mineverse.com/threads/important-announcement.115232/#post-1124262 If you don’t want to logon the server again, don’t download it. This is the only way some people can logon...
@Watermelonone some people have connective issues due to there Internet and this bypasses that unless you have another way I highly suggest you do this.
See it was your internet, I am glad you got it fixed. @Watermelonone maube try a VPN, as it work for him.
