Hi @iamartwo, thank you for a very thorough post. Is it a 512 or a 521 that you found on the 6 files? I’ve not seen a 512 before, there are some mentions on this site but the posts appear to be about 521 errors. The last quick fix idea in this tip may apply, Community Tip - Fixing Error 522: Connection timed out, although that’d be the first time I’ve actually see that situation.
