  That's the conclusion I had come to. Windows PC wouldn't load the maps using Virgin broadband, but connecting via the  phone hotspot and mobile network they loaded fine.

  Hi everyone,

  I've just read all the replies to the emails I sent out yesterday and the common denominator is Virgin ISP.

  After a search online, it seems that similar issues have been raised on several forums by Virgin clients.

  Please give the below workaround a try and update this post to tell me if it works.

  All the best,

  Julien

   

  Blank Map Issue with Virgin Media

  Virgin Media sometimes enables its Web Safe / Child Safe filter by default. This filter can block our map-tile servers and cause the browser error “ERR_SSL_PROTOCOL_ERROR.”

  1. Sign in to My Virgin Media → Broadband → Web Safe.

  2. Switch Child Safe and Virus Safe to Off, save, and restart your router.

  3. If you’d rather keep Web Safe on, simply change your device’s DNS settings to 8.8.8.8 (Google) or 1.1.1.1(Cloudflare).

  4. Reload the page—your map should now display

  Same effect on my iPhone.

  Well, that's interesting...  The mention of VPN just made me try switching my iPad icloud Private Relay back on (I switched it off a while back as I thought, incorrectly, that it was slowing the connection down).  As soon as I switched it on, all the maps were available and downloading correctly.

  Hi!

  Sorry for not updating you sooner. I was away for a bit and meanwhile the devs kept looking into this issue with the help of the community.

  We do not have a fix yet, because we still need to pinpoint the origin of this issue.

  So far, we think that the issue is location-specific.

  Some of you reported that map layers did work using the following workarounds:

  • using Tor Browser
  • using a Chrome extension VPN with hosts in mainland Europe

  I have just sent out several emails to some of you to keep gathering information.

  Thanks for your help and your patience.

  Any progress with the blank Cycle (the one I use the most) and OS maps?

  Still going on. IOS, Chrome, Edge. No different. Also the trails map.. Incognito too..

  Hi everyone,

  Just an update to let you know that the devs are still investigating.

  I have just sent out several messages to those of you who got in touch via email, asking for your help with further tests.

  As soon as we have a fix, I'll update this topic again.

  Thanks for your help!

  That really sounds like a glitch with you "Premium" account .... I have been using the OS maps a lot recently, and no issues.

  I still can't, though I thought the problem had been resolved when all three reappeared for a brief period (minutes or, perhaps, hours). There have also been a couple of instances of partial tiling but ultimately, depressing greyness. The phone app also gives the same result.
