SSL calls although http:// protocol used (iOS)

#1

Hi all,

we observed in our nginx logs that calls are SSL-encrypted, although we did not specify any SSL connection (just http). While I cannot see that during debugging, some phones seem to try SSL instead of plain http.
I am still digging in the code. But if anyone has an idea, please let me know.

Best
Ulf

Every 15 minutes, we observe this (4 calls, one per second) coming from the couchbase library. Any explanations?
