/var/log/roundcube
There are no files in this location at all
including log file
please be more descriptive about your system/setup. what components did you install? which versions are you using, did it work before? what was the last change/interaction (like any updates) you did before it stopped working etc.
if it seems the error logs are empty, check the access logs for the same domain and timestamp to see if there accesses logged at all.
do you use a proxy or cloudflare or something like that? if you do not see anything in the logfiles maybe the request does not even reach your server, but stops somewhere before already.
other than that such internal errors often are either permission things or failed database access. however those you will find in some logfile after all.
Hello, Falzo!
Thanks for your thoughtful look into my problem.
And that’s how it was.
We use HestiaCP ten servers. Everything is great.
And here we are taking a new server in April
4 CPU 16Gb RAM 1Tb HDD
Immediately we made an update to the Ubuntu system
apt-get upgrade
Then the installation of HestiaCP is successful.
The next activity mark is the creation of the DNS server.
Master server and slave. At the same time, we were finally able to synchronize the Slave DNS on one IP address with another Master.
When we delegated the domain and waited for our NS1 to come into force, NS2 was very happy and celebrated with a glass of red semi-sweet wine.
After we went through the Ubuntu update again, since
when logging into the console, a message appeared with the option to update.
apt-get upgrade
When we now host a new domain, we can delegate it to our NS servers.
It’s time to delegate the domain, for which we began to create mail.
And so, as always, to check the operation of mail on a new domain, we follow the link from the panel and get an error message.
Early we rejoiced, we thought 
Once again, we launched the installation of the roundcube,
apt install roundcube
but the installation was interrupted by a message that we already have the base.
That’s all we’ve done up until today.
Yesterday, only, was a good day off, and it was wonderful to spend it in the country.
Today again we are alone with this problem
With best regards?,
Don’t install roundcube via apt(-update)
We use our own “installer” run the upgrade script in /usr/local/hestia/install/upgrade/manaual/
Run the script
migrate_roundcube.sh ?
Yes …
Ok
Script started successfully

The situation remains the same…
Sending mail is working, the Thunderbird client is connected and letters are successfully sent and reach the address
Now check /var/log/roundcube folder it should have log files…
And /var/log/nginx/domain/mail.domain.error.log / /var/log/nginx/domain/mail.domain.error.log
or
/var/log/apache/domain/mail.domain.error.log
/var/log/apache2/domain/webmail.domain.error.log
This file contains 0 kB
webmail files are missing in this directory
This file contains nothing close to a roundcube
/var/log/apache2/domain/domain.error.log
Hello, friends!
A problem still stands in the way of safely surfing the delights of life
I would be very happy with advice on how to diagnose roundcube malfunctions
Without any error logs or anything other information I have no ideas.
This reminds me of a famous anecdote.
Two friends meet and one says:
“I haven’t eaten in days, how are you?”
And he answers:
“I’m fine, business is booming, but the fact that you don’t eat is bad, you have to force yourself :)”
Is this a developer specific answer
chicken laugh
You chicken laugh developer, tell your girlfriend this tonight :) I’m chicken laugh
Otherwise, how can I interpret your words
“Without logs, I can’t take an idea”
What I’ve been trying to ask all week
not otherwise than
- “Please tell me, my friends, which log file to read in order to understand the problem?”
It was with this question that I turned to the branch, or not ???
Is this a developer forum, if I’m not mistaken, or friends, drink beer?
The product for which you have your own install script has failed!
And you look at it, lazily rubbing your eyes?
“Without logs, we can’t know who we are”
– “And we without logs, what can we do?”
Hestia is opensource project and comes without any warranty or support
See our License:
As you have already 10 servers we should assume you have basic knowledge on how Hestia works.
We don’t have any access to your server and we don’t want it. But we are not able to “guess” what is wrong.
If you want to pay 100 USD an hour please feel free to send me a DM. But without more information I can’t do anything.
Please, excuse me, kind, decent colleagues! Including you, dear developer
I really kneel in front of you because your product is very successful and you are just great
Yes
For all of our 10 servers, we experience orgasms when we use your product because it is the ultimate in excellence and challenges the mossy and sour community of panel owners
from year to year sucking money out of users of hosting owners and server tenants.
But your fork is so successful that it spoiled me and made me lazy and careless because everything is very good
Super works well!
and when i earn 100 dollars i will send you monthly just like that
Please read the book of Ecclesiastes
It will open your mind
And look on YouTube Mikael Lightman
And I am ready to worship your product because it is perfect, its code is flawless and it works very well!!!
You are absolutely right
