Any updates on this? Myself and many others in my organization have also been receiving this same error message (Http failure response for https://survey123.arcgis.com/api/reportMerge/_printByWordTemplate/execute: 502 OK). The strange thing is that if this error message is received, but we try repeatedly to generate the report, we sometimes, although not always, are able to generate it on subsequent tries. Sometimes it takes quite a few. We originally thought this might be associated with internet speed for users working remotely, but the same thing happens with fast connections. Occasionally, some surveys won't generate at all. This is not restricted to one specific survey. It is happening with many of them. We started experiencing this problem just within the last month.
