perl modules failing to install

Question

I was writing a perl script and realised I needed to get some additional modules, so I used the command:

$ cpan List::MoreUtils                                                                                                             

and got back:

Please check, if the URLs I found in your configuration file
(http://www.cpan.org/) are valid. The urllist can be edited. E.g. with 'o
conf urllist push ftp://myurl/'

It's not like I've not downloaded other modules before. I'm not sure what's going on. Says "Service Unavailable 503". Yet, I can go to the URLs stated in the log above directly with my browser and download the file.

Trying to use the wget command directly results in the same issue.

I'm using MSYS2. What could be going on here? Is there something wrong with the cpan site?

Edit

Things I've tried are:

1. Adding mirrors as shown here .
2. Attempted to do a full system upgrade as shown here .
3. Tried to use a Ubuntu WSL to do the same thing.
4. Tried to use my phone's data network to confirm that it wasn't caused by a firewall issue.

No joy. 😔

Can someone at least comment to say if they are having the same issues by doing a test module install?

Answer 1

Grrr. When I had attached to my phone, it's WiFi was connected to my local network and so had the same issue. Once I put it to only the cell network, it worked fine. Seems that this is caused by some change to our corporate firewall. 😠

Still doesn't explain why I could get to the file directly through the browser but couldn't using wget though.
