HTTP failures browsing site with iPhone/IOS

datazen commented 4 years ago

Current behavior

Http failure with iPhone/IOS is being reported in our error logs. (using stacktrace)

ERROR:
Http failure response for /assets/i18n/en.json: 0 Unknown Error

AGENT:
Mozilla/5.0 (iPhone; CPU iPhone OS 13_2_2 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/13.0.3 Mobile/15E148 Safari/604.1

Expected behavior

No Http errors reported

How do you think that we should fix this?

Perhaps setup the same environment and use same user agent to re-create the issue.

Minimal reproduction of the problem with instructions

We have had this issue since converting to Angular 7 from AngularJS. Only happens when site is browsed using IPhone/IOS and is possibly intermittent. We have error reporting in place and the above is what gets reported. Why the failure I do not know.
