For official bootstrap nodes:
rabinovitch@lotus:~$ telnet bootstrap-0.taurus.subspace.network 30333
Trying 65.108.232.56...
^C
rabinovitch@lotus:~$ telnet bootstrap-1.taurus.subspace.network 30333
Trying 65.108.71.22...
^C
Jist “Trying” with no result.
For vexr’s node:
rabinovitch@lotus:~$ telnet bootstrap-0.evm.taurus.ai3.farm 30333
Trying 50.125.83.156...
telnet: Unable to connect to remote host: Connection refused
OK, that looks like you cannot access the official bootstrap nodes and possibly vexr’s is down or the port has been closed.
The problem accessing the bootstrap nodes is your root cause.
Maybe this will be helpful:
rabinovitch@lotus:~$ telnet bootstrap-0.mainnet.subspace.network 30333
Trying 65.108.228.84...
^C
rabinovitch@lotus:~$ telnet bootstrap-2.mainnet.subspace.network 30333

Perhaps if there were more bootstrap nodes, then there would be no problems with Taurus.
Here are some unofficial bootstrap nodes that can help. Note that they are not on the standard port 30333.

And it really helps:

My best guess here that your ISP has blocked the Taurus bootnodes. You could reach out to them to ask why and request the restriction is removed.
For me too
