Hi.

It seems like maybe the server is not able to connect to itself, for some reason....well, not really, I tried to connect to it from here and I can't either, using a simple script with file_get_contents, no idea why.
Are you using file_get_contents or cURL? If using file_get_contents, you could try using cURL to see if that helps.

I am using file_get_contents. I have requested the hosting provider to update me if they have changed anything at the server side. They did something and now it is working fine.

Great to know it is working. It would be good for you what they change, though, in case it happens again in the future and you need to get hosting support to look into it.
