Issue webserver configuration troublshooter weird error

[stas styler]

Hello,

I'm running Centos7.4 + Plesk Onyx 17.5.3 Update #30 + NGINX as reverse proxy over a VPS hosted in hetzner.
My server is 32GB ram, 8vcores.

I configured basic global gzip.conf + added some tweaks to nginx.conf and started adding domains.
I've had some problems that occurred some time after I've added a reseller domain.
The file "ulimit.global_params" gave me red notice in plesk that there was a duplicate worker_rlimit so I just tagged it in "ulimit.global_params" as suggested in kb.plesk.

couple of days later it occurred once again after I've added another reseller (as you can see I have 2 tagged lines in the screenshot of "ulimit.global_params".

All my subscriptions became with a red earth icon so I just reconfigured everything and tagged once again the line of "worker_rlimit_nofile 4096;"

All my domains were pointed to default plesk page even though all files were in place. So I went though all domains and, accessed to "apage & nginx setting" and pressed apply so it would reconfigure each one.

now I have this error:

Error: New configuration files for the Apache web server were not created due to the errors in configuration templates: nginx: [emerg] duplicate listen options for [2a01:4f8:c0c:40c1::2]:80 in /etc/nginx/plesk.conf.d/server.conf:29 nginx: configuration file /etc/nginx/nginx.conf test failed. Search in KB

and a weird red "/" with no path and n/a.

all domains work fine, it just worries me and I just can't understand what seems to be the problem now.
I don't know what caused the duplication either.

Can someone please help me?

What is content of line 29 in /etc/nginx/plesk.conf.d/server.conf ?

To be fare, I don't use IPV6 for my domains.

Please do not send screenshots of your configs, it is impossible to copy-paste from pictures in answers. Please use plain text instead of pictures! Thanks.

The problem in duplicated listen options for [2a01:4f8:c0c:40c1::2]:80. You need to remove it from /etc/nginx/plesk.conf.d/server.conf or another conflicted config.

Try to find all entries with something like

# grep -R '[2a01:4f8:c0c:40c1::2]:80' /etc/nginx/*

BTW, command

# plesk repair web

also may be useful.

But this file overrides as it says on top of it doesn't it?

Do you have this line specified in Additional nginx directives in Plesk UI?
