Same problem - has been happening since around the server upgrade. Will be able to read fine for a while and then images just stop loading. Especially noticeable on long strip manga - some pages will load and others always fail despite reloading (not in sequence). Have tried the fixes besides...
Thank you so much for this option - I primarily read on my phone and I barely notice the quality difference. Meanwhile, pages are loading faster than ever!
Thanks for all of the good work. It's great to see Mangadex become a worthy successor to Batoto, and I hope that Mangadex is around for many more years to come
