"Network Error" when submitting pending .exe file

Please see the attached image. I get this error when trying to submit a file. The file seems to get successfully prepared (compressed) for submission, but then the transfer is about to begin, I get the error. It happened yesterday evening and today, with the same file.

What do you think - temporary problem at Comodo’s receiving server, or something wrong with my system? In case the submission feature depends on a Windows service, or maybe Internet Explorer (like the CIS updater) it’s more likely that there’s something wrong with my machine.

Even in my case this happened yesterday and hence I zipped and mailed the file to malwaresubmit.

OK, thx for confirming.
