If you're a Rogers customer who has received a strange "proxy authentication required" pop-up this morning, congratulations! You're one of an unknown number of Canadians dealing with yet another baffling service issue from the provider, which is still recovering after that nationwide outage that brought cities to a halt last year.

Rogers confirms to blogTO that the MMS issue was resolved around 11 a.m. Thursday.

It appears that along with recent disruptions to internet service just outside Toronto, some residents are finding themselves unable to send SMS and MMS messages in group text conversations.

Good morning Peter. We've received reports of some customers experiencing an issue sending MMS messages and our network team is working to resolve as quickly as possible. Thank you for your understanding and patience. ^ BE

These types of messages have been bouncing back with a "not delivered" alert, with both text and photos/videos not able to go through.

Customers are also being prompted to enter a username and password for an HTTP proxy — something many have never seen before.

The peculiar pop-up lists the proxy "mmsproxy.rogers.com:80" and directs people to go to their phone's settings to fix the issue.

I have the same thing as does two of my coworkers.

A slew of users took to Twitter early Thursday to complain about the confounding problem, and in response, Rogers customer service reps are issuing a statement that at least acknowledges the ongoing difficulties, but does not explain them further or provide a time that things may be fixed.

"We've received reports of some customers experiencing an issue sending MMS messages and our network team is working to resolve as quickly as possible. Thank you for your understanding and patience," the @RogersHelps account said to multiple individuals.

The company also confirmed an earlier internet outage yesterday in Alliston, Bolton, Orillia and Orangeville, which has since been resolved. Internet users in North York, Whitby, downtown Toronto and other parts of the province still claim to be encountering the same trouble today, though, based on social media grumblings.

A Rogers representative has also since informed blogTO that shortly after 11 a.m. Thursday, the MMS item has also been resolved.
