Hi Bob,
Which version of SOGo and SOPE are you using?
Thanks,

Michel,
Thanks for your response.
The Sogo logs don't appear to address the problem. I am seeing the
error "No child available to handle incoming request!" around the time
of the connection attempt, but I can't match it with the configuration
attempt.
The users aren't using Office, they are using the ActiveSync support
included with iOS and Android.
I'm not certain if I understand your third point. The URL I'm using
is https. We have a CA signed cert installed in Nginx.
Since I posted my original message I've done a lot of additional
troubleshooting. It seems like the "No child available to handle
incoming request!" error may indicate there aren't enough child
processes available. I've tried increasing WOWorkerCount
unsuccessfully. When I attempt to increase this count I begin
obtaining the "sogod [1716]: [ERROR] <0x0x5595d0273e50[WOHttpAdaptor]>
failure notifying watchdog we are ready during events registration:
<NGSocketShutdownDuringWriteException: 0x5595d0273770>
NAME:NGSocketShutdownDuringWriteException REASON:the socket was
shutdown INFO:{errno = 32; error = "Broken pipe"; stream = "{object =
0x5595d03818f0;}"; }" error.
I'm able to start exactly 508 workers. When I attempt 509 workers
the error appears and SOGo shutdown quickly after startup.
I believe this may be OS related but I can't solve it. I've changed
/etc/security/limits.d/20-nproc.conf to include:
sogo soft nproc unlimited
sogoeas soft nproc unlimited
root soft nproc unlimited
No difference.
I’ve also tried changing /etc/security/limits.conf to include:
sogo - stack 32768
sogo - nproc 8192
sogoeas - stack 32768
sogoeas - nproc 8192
Again, no change.
I'm researching thread/process limits per user in Linux. So far I
haven't had any success.
Thanks again,
Bob

Hello
3 things
First thing, what does Sogo's logs say?
Second thing, the Office version, is that the last one?
3rd thing, when you add the URL with the subdomain with
/Microsoft-Server-ActiveSync, you add it without the "https",
because if you add it, was that my mistake, it actually adds an
error message.
Have a good day

We've recently begun receiving reports from some of our
students indicating they can't configure their phones to
access Sogo. I've verified this using iOS and an
encountering the problem as well.
Users select to add a Microsoft Exchange account, enter their
e-mail address, select to configure manually when prompted,
enter their password when prompted, then click next. iOS
displays "Verifying..." for a few seconds and then prompts for
more information. They enter the correct server, username,
and password then click next. After a pause of about a
minute with "Verifying" displayed the error "Unable to verify
account information" appears.
I've been checking both my nginx and sogo logs and can't find
any details on the problem.
I'm running a separate instance for eas traffic as specified

The nginx logs are showing a LOT of ActiveSync traffic. I
believe this problem is related to something in my
configuration, not users ability to access our server. It
appears users who have preexisting configs are fine. New
users can’t seem to configure their devices.
I am seeing the following errors within my SOGo log:
Nov 06 10:05:45 sogod [32707]: [ERROR]
<0x0x55720946ebf0[WOWatchDog]> No child available to handle
incoming request!
We have a large number of users accessing the EAS instance.
I initially had the WOWorkersCount for the eas instance set to
400. I have it set to 500 now. When I try setting it
higher I encounter the following error in the SOGo log:
sogod [1716]: [ERROR] <0x0x5595d0273e50[WOHttpAdaptor]>
failure notifying watchdog we are ready during events
registration: <NGSocketShutdownDuringWriteException:
0x5595d0273770> NAME:NGSocketShutdownDuringWriteException
REASON:the socket was shutdown INFO:{errno = 32; error =
"Broken pipe"; stream = "{object = 0x5595d03818f0;}"; }
I’m going to investigate any OS related limits which may be
causing this problem. Could lack of threads be preventing
new users from configuring their devices?
Does anyone have any suggestions on what I should look for
while troubleshooting this problem?
Thanks,
Bob
