Xfinity sign in from the app is nonfunctional suddenly

, ,
1

— I have brave set as the default browser on my iPhone 12 for many months. The Xfinity app uses the default browser to sign in at login.xfinity.com. I’ve been having problems with everything and last night I found that port 22 ssh was open on my router. There is no way to close it even after ten hours of runaround with Xfinity. In the meantime I was logging in and out of the Xfinity app where you can control the router and my access suddenly stopped working. The page asks for username phone or email and when you enter any of the three it loops back to the same screen asking for the same thing again. You cannot get to the next page where it asks for a password so you cannot access the Xfinity app. I cleared cash cookies and everything possible from the brave browser, closed it and reopened and the problem persists. I tried the same page in Firefox focus, and on desktop and the web page works fine on other platforms. The app even works with brave as default in my iPad just not on the phone and quite suddenly. That either limits the problem to an interaction between the iPhone and brave or just my phone and brave I’m not sure which. I’ve run out of things to try having deleted and reinstalled the apps multiple times and cleared everting twice including shredding the site data. I’m hoping someone here smarter than me can find a problem and fix it and that it is not a problem that is specific to my phone only. I an very suspicious that someone is causing these problems because I have had a very large number of unexplained issues over the past month or so that started with unauthorized devices signing into my Google account. I think it may have all started with the unauthorized opening of port 22 on my router which did not have default credentials in use. This his is my first time here so if this is done wrong I apologize, I did read through the directions but all I seem to find to give information is this field. If the admins could tell me if they find anything that would be awesome if not I’ll survive. Have a great day to whomever might eventually read this.

Also the problem exists/persists in private mode and there are no extensions on thimble version to turn off

Brave Browser (iOS)

Somewhere between 4 and 5 occasions during the last 5 years, I have made sure to back up all of my Brave Browser (iOS) data, and then completely un-installed Brave Browser - including all data other than the backup - followed by:

How to do a Complete Exit / Quit of iOS apps; and choices of, Power Off, Soft Restart, or “hard” / “forced” Shutdowns:

Apple iOS - iPhone - completely quit an app:

Apple iOS - iPhone - soft restart - steps to reveal the Power Off slider:

Apple iOS - iPhone - complete, “forced”, “hard” restart:
-https://support.apple.com/guide/iphone/force-restart-iphone-iph8903c3ee6/ios

Apple iOS - iPad - soft restart - steps to reveal the Power Off slider:
“To turn off any model, you can go to Settings > General > Shut Down, then drag the slider.”
-https://support.apple.com/guide/ipad/turn-ipad-on-or-off-ipad63d30b5a/ipados

Apple iOS - iPad - “forced” restart:
-https://support.apple.com/guide/ipad/force-restart-ipad-ipad9955c007/18.0/ipados/18.0

On other occasions of “some kind of issue” with the iPhone, I also use those steps to completely / thoroughly restart the iPhone via full Power Off, pause for 30 seconds, Start up the iPhone.

That solved a lot of issues with the iPhone.

IF the above steps do not work, I would use, as you did, Firefox Focus (iOS), or possibly Vivaldi (iOS).

Tips regarding Brave Shields:

I have more success, with:

  • Brave Shields UP, but . . .
  • Either Allow All Cookies or Block 3rd Party Cookies, but NOT Blocking All Cookies
  • Allowing JavaScripts from specific sources, but NOT Allowing All JavaScripts
  • Trackers & Ads treatment: Aggressive (at first), and then incrementally relaxing that setting
  • Fingerprinting (aka footprinting) blocking: Strict (at first), and then incrementally relaxing that setting

I almost NEVER use:

  • All of Brave Shields UP
  • All of Brave Shields DOWN

Shields Basics

How do I configure global and site-specific Shields settings?

How do I use Shields while browsing?

Intended for study >

Following applies to the Brave Browser desktop -type installation . . .

Exit / Quit Brave Browser and set some other Internet browser as the default.

Exit / Quit everything and Restart computer.

Next, 7 Steps . . .

  1. Visit https://www.xfinity.com
  2. Click the “tune” icon to the left of the https in the URL address field
  3. In the pop-down menu, click Site settings
  4. In the resulting Site Settings Details window, click on Delete data
  5. Next, in the same Site Settings Details window, click on Reset permissions
  6. Close the settings page.
  7. Reload the https://www.xfinity.com webpage

Notes:

  • Tune icon: Tune_button_left_offset_of_URL_address_field
  • Site Settings Details window link: brave://settings/content/siteDetails?site=https%3A%2F%2Fwww.xfinity.com

In a Brave Browser New Window, go to: brave://settings/content/javascript

Scroll down that javascript settings page to Allowed to use javascript

Click the Add button

Enter [*.]xfinity.com as the site . . . but do not Enable the following:

  • Current Private session only

Click the Add button

Repeat for the following ‘XFinity ecosystem’ domains that are all sources of JavaScripts:

  • [*.]assets.xfinity.com
  • [*.]cdn.comcast.com
  • [*.]cobrowse.xchat.xfinity.com
  • [*.]dl.cws.xfinity.com
  • [*.]login.xfinity.com
  • [*.]media.xchat.xfinity.com
  • [*.]metrics.xfinity.com
  • [*.]oauth.xfinity.com
  • [*.]polaris.xfinity.com
  • [*.]static.cimconent.net
  • [*.]www.xfinity.com
  • [*.]xchat.xfinity.com

Also make sure those domains are not blocked ← by firewall, hosts file, quarantine, software?

Note: I used Brave Browser > Developer Tools > Network [tab] window, etc., in order to find all of those hosts that are sources of JavaScripts.

Now, set Brave Browser as the default Internet browser.

Exit / Quit Brave Browser. Restart computer.

In a Brave Browser New Window, go to: brave://settings/content/braveShields and, in the Shields Down section, Add: www.xfinity.com , and next, while still there, also add: login.xfinity.com

So, in contrast to using the Brave Browser Site-Specific Shields settings (that you get to by clicking the Lion icon near the right end of the URL address field) . . . you are establishing the 2 settings at brave://settings/content/braveShields, in order for the Shields DOWN setting to stick ← during whatever reloading and shuffling around occurs.

In the case of trying to sign on, I suggest first visiting https://www.xfinity.com and there, click on the Sign In button that is in the upper-right corner of that webpage. I would not go directly to https://login.xfinity.com.

Try to sign into XFinity.
