sometimes connection refused, but ends in fatal error

[kruegge82]

Describe the bug
one call it works, next call not... i searched for a reason but cannot find.
Its the check function if connection exists.
Should it end in an fatal error if connection really refused?

If the server randomly refuses connections, it's most likely a limitation on the server side.

You should wrap send/receive calls in a try/catch clause to handle various errors that might occur.
