I think a lot of the connection issues described in this thread are because only two of seven CWOP servers have been up the past few weeks to months.
If you look at the bottom of
http://status.aprs2.net/, only two of the servers are running.
Per long-standing Standard Operating Procedure (SOP), cwop.aprs.net points to a set of four servers in a round-robin fashion, only two of which have been running.
See:
http://www.wxqa.com/cwop_info.htm"Data are forwarded to the CWOP servers, using the round-robin domain "cwop.aprs.net" port 14580"
Here is a companion thread I started yesterday in the CWOP section:
https://www.wxforum.net/index.php?topic=44363.msg451175#msg451175Gory Details using nslookup on Linux:
CWOP.APRS.NET rotates among the same four servers
]$ nslookup cwop.aprs.net
Server: 127.0.0.53
Address: 127.0.0.53#53
Non-authoritative answer:
Name: cwop.aprs.net
Address: 44.155.254.4
Name: cwop.aprs.net
Address: 85.188.1.27
Name: cwop.aprs.net
Address: 129.15.108.116
Name: cwop.aprs.net
Address: 129.15.108.117
First response to nslookup for CWOP.APRS.NET gives a different one of
the four first:
]$ nslookup cwop.aprs.net
Server: 127.0.0.53
Address: 127.0.0.53#53
Non-authoritative answer:

Note only two of the above have been working recently,
* 44.155.254.4 (cwop.ei3rcw.ampr.org)
* 85.188.1.27 (cwop.he.fi)
