Hello everyone,
After installing ottoFMS on several Macs, I am unable to access the application via “localhost/otto”, “servername/otto”, or “domain/otto”; access is only possible through http://127.0.0.1:3061/otto/.
This suggests that the proxy may not be functioning correctly. Restarting the server, proxy, and FileMaker Server has not resolved the issue. Are any changes required in the proxy configuration, or could there be another reason for this problem?
Thanks for the Help.
Hey @hgi_voegel ,
Welcome in! Which version of OttoFMS did you install? You should not need to make any manual changes to the proxy setup, OttoFMS makes them when it boots up. Do you see any logs in the otto-info.log when you restart OttoFMS? It should have a number of logs about setting up the reverse proxy.

Hey @kduval Thanks for the reply,

According to the logs, the proxy appears to be set up correctly and no errors are reported initially. However, once the server is running and I attempt to access the page, the recorded error messages occur.
We are currently using version 4.13.1, which, to my knowledge, should be the latest version, correct?
Also Thanks for helping us out.
Hey @hgi_voegel ,
Do the timestamps of the “Can not connect from a remote address” error in the log correspond with the times you try to access it from a non-localhost address? That is the error which should be appearing when you attempt to access directly via localhost.
Have you made any changes to the filemaker http setup other than what OttoFMS does?
-Kyle
Hi @kduval,
I encounter the “Can not connect from a remote address” error whenever I try to access the /otto page, whether I use localhost, servername.local, or the domain. The only way it works is by going to 127.0.0.1:3061/otto. Interestingly, on Windows machines, we can access the Otto dashboard without any issues using both localhost and the domain.
Do you have any idea what might be causing this? We’re a bit stuck.
Hey @hgi_voegel ,
Could you send me a copy of your /Library/FileMaker Server/HTTPServer/conf/httpd.conf file and your /Library/FileMaker Server/HTTPServer/conf/extra/httpd-otto-proxy.conf file? That seems like a proxy issue, although a fresh install shouldn’t break anything in there.
Also, are there any firewalls or network configuration changes on the server?
-Kyle
Hi @kduval,
the Firewall is disabled on the Mac,
Additionally, there have been no other network configuration changes on the Mac, aside from setting a static IP address.
here is the conf file,
Thank you for your Time.
httpd.conf
#
# This is the main Apache HTTP server configuration file. It contains the
# configuration directives that give the server its instructions.
# See <URL:http://httpd.apache.org/docs/2.4/> for detailed information.
# In particular, see
# <URL:http://httpd.apache.org/docs/2.4/mod/directives.html>
# for a discussion of each configuration directive.
#
# Do NOT simply read the instructions in here without understanding
# what they do. They're here only as hints or reminders. If you are unsure
# consult the online docs. You have been warned.
#
# Configuration and logfile names: If the filenames you specify for many
# of the server's control files begin with "/" (or "drive:/" for Win32), the
# server will use that explicit path. If the filenames do *not* begin
# with "/", the value of ServerRoot is prepended -- so "logs/access_log"
# with ServerRoot set to "/usr/local/apache2" will be interpreted by the
# server as "/usr/local/apache2/logs/access_log", whereas "/logs/access_log"
# will be interpreted as '/logs/access_log'.
#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# Do not add a slash at the end of the directory path. If you point
# ServerRoot at a non-local disk, be sure to specify a local disk on the
# Mutex directive, if file-based mutexes are used. If you wish to share the
# same ServerRoot for multiple httpd daemons, you will need to change at
# least PidFile.
#
ServerRoot "${HTTP_ROOT}"
#
# Mutex: Allows you to set the mutex mechanism and mutex file directory
# for individual mutexes, or change the global defaults
#
# Uncomment and change the directory if mutexes are file-based and the default
# mutex file directory is not on a local disk or is not appropriate for some
# other reason.
#
# Mutex default:/private/var/run
#
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the <VirtualHost>
# directive.
#
# Change this to Listen on specific IP addresses as shown below to
# prevent Apache from glomming onto all bound IP addresses.

Hi, on a Mac Mini M4 , unfortunatelly i have te same error ( and i have intsall otto probably more than 80 times in different machine … )
@alecorticelli Do you have anything in your logs or http conf files that is different than the rest of the thread? Is OttoFMS accessible from the 127 hostname on the machine? Do you have anything else installed on the mac that is changing the http setup for FileMaker?
-Kyle
hi, my configuration is standard an dowrk on the old server, unfortunatelly for a problem on the NIC i was obbliged to change hardware all works . only OTTO not lunch i see taht may be is a problem with the ssl, i got some truble to install , but now is greate and otto conine to not load . i hev full disinstall several time and try to install using siliocn app and terminal …
if you want we can make a quick zoom video sharing on the server, let me know!
If you want to make a video to send along I’ll look. I’ll also need to see the otto-info.log and what you see when you try to load OttoFMS.
-Kyle
video of what ?
of the error ?
i send here ?
I’ll need the error and the logs. Screenshots and copies of the logs will probably be easier to send than a video.
-Kyle
the logs of filemaker or the isnatlelr of otto can you share the location of otto please?
here the OTTOlogs
OTTOlogs.zip (4.3 KB)
Your logs look like OttoFMS is working properly, the screenshot you sent it of the base path on the filemaker server. What do you see when you go to https://server.hostname/otto/app/ ?
-Kyle
with your url load ottofms, but in the other server y simply use localhost/otto/ and he laod everythigs why this opne i need to specify app ?
