As you can tell by the title if you are having connecting issues it is probably because of your Internet or that Mineverse Is BlackListed again.
Here are some ways to connect to mineverse again.
Before reading this one of the Owners has made a thread about this and may be more helpful check it out. Click here.

SquidHQ - Click here.
SquidHQ is another version of Minecraft that allows you to join any blacklisted server without a problem. Some people have tried this and still can’t connect.

Try connecting with another Minecraft Domain.
Mineverse has multiple domains you can try to connect too. Such as listed here.
Mineverse.com/net/org
Skywars.com

Restarting your Router.
Some people have complained about this and restarted there router and it fixed. For some people this still did not work.

Get a VPN or Turn off your VPN.
What I mean by this is that if you don’t already have a VPN, maybe getting one could be your issue. If you don’t know how to get a VPN, it’s simple and easy go to your Browers store and find a free one.
Other people are running multiple VPN’s and this could be the issue with some people’s connection. Maybe turn them off or turn a few off. Could fix your problem.

Contact an Administrator or wait until Mineverse is UnBlacklisted.
If you have tried all these, I highly suggest contacting an Administrator and see what information they can give you or you can simply wait until mineverse has been UnBlacklisted.
I am sorry if you have to wait.
Here are some Administrators you can contact,

I wasn’t able to logon, but after I downloaded squidhq I was able to. Mineverse is probably blacklisted again.

 

Yeah, I assumed so. I am glad you could connect.

 

It is blacklisted.
Matt is fixing the issue currently.

Shouldn't be long.
Thanks for your patience.

 

It is working fine for me and many more.
Either way Matt is working on it.

I am so sorry for the wait.

 

I just reset my router and it didn't work.

 

Did you try using SquidHQ? It is working good for me and many other people. I am glad Matt is working on it. @yeahsquirrel the problem should be fixed soon.

 

SquidHQ doesn't fully download for me.

 

Many people are joining without SquidHQ, I believe the blacklist is down.

 

Could you explain more?

 

@SniffMyToes I don't think the Issue is resolved, I tried join with a normal client and I cannot join. I think Pile will tell us when the issue is resolved.

 

So basically when I try downloading it, it stops a 3rd of the way on the last portion of downloading.

 

Mhm, maybe try downloading off a different browser. Also check if you already have it downloaded into your PC.

 

Should be fixed now.
Thanks guys for your patience.

 

Unfortunately, even on a different browser it does not work.

 

Try logging in with your normal minecraft launcher, Pile said it was fixed. @Pile thank you.

 

It still does not work for me.

 

Mhm, have you tried all the steps listed above? If so, I do think you should try a regular launcher again or restart you pc. I don't know if this will help. I suggest contacting one if the developers or admins to help you. I wish I could help.
