I am currently having problems visiting archive.org
Safari 12 (and 13 b4) on Mojave shows the following error:
kCFErrorDomainCFNetwork error 303
Things I've tried:
- disable all extensions
- Develop > Empty Caches
- trashing Safari.plist
- booting into Safe Mode
- recovery mode + Disk Utility First Aid
- different DNS servers
All have had no effect.
Strangely, the problem does not appear in Safari Technology Preview, Chrome, Opera or Tor.
