Versions: Apache/2.4.10 (Raspbian) PHP/5.6.30-0+deb8u1 OpenSSL/1.0.1t
From linux console, testing the ssl timeout:
time openssl s_client -connect x.y.z:443
...
Start Time: 1504204638
Timeout : 300 (sec)
Verify return code: 0 (ok)
---
(delay of about 20 secs)
----
read:errno=0
real 0m20.903s
user 0m0.050s
sys 0m0.000s
When the above test was done, error log shows (in debug level setting)

Image upload , even small files, times out after about 15 secs, independent of the following (see two settings tried)
# the following is an expt, setting very low to see if this statement has any effect at all. We get time out after 15 secs, for any setting.
#RequestReadTimeout header=5 body=9
RequestReadTimeout header=60-100,MinRate=50 body=80,MinRate=50
For the actual timeouts during timeout in the apache 2.4 error.log (With either of the above settings,the time out is pretty much the same 15 sec.; only one log is shown below)
