I have a Laravel 7 project on the Ubuntu + Nginx server. I can upload files less than ~10mb, but when i am trying to upload a 120mb file I got an error. I am already changed memory_limit, upload_max_filesize, post_size to 640mb in php.ini. It did not help. I am also restart php-fpm and nginx services.

The problem was in the less memory of the server. After I increase it from 5GB to 10GB there is no problems. But before that there was about 200MB and I tried to upload a video of 100MB
I have done a fresh installation of WordPress on AWS Elastic BeanStalk.
I am not using the root directory. I have moved the WordPress code to the public directory.
I am not able to open the page to add or edit the post/page.
I am getting the below error in Nginx logs.
I tried both WordPress 5.5.3 and 5.4.4
Any clue where the issue can be?

The issue was caused by git. I am using composer with WordPress, so had added the 'vendor/' entry in the .gitignore file.
Because of this none of the vendor folders were getting shipped to the server and hence the missing files.
I changed 'vendor/' to '/vendor' in .gitignore file. Ran 'git rm -r --cached .' and committed the code again.
It works now.
I do not have a server running, error 502 within 25 minutes, I see the following in the logs:

I found the following discussion that was posted 4 years ago: 502 Gateway Errors under High Load (nginx/php-fpm)
Where someone had a similar issue as mine, but unfortunately I believe that the configurations he received were customized for his own server specs and I can't use the same configuration on my server. Anyway I would like to present the problem I have by myself and not to just tell you to go to the link I sent and read someone else's problem.
So to my own story - I have a big social media page where I post links to my website articles, which means that I have lots of traffic spikes during the day each time I share something. Recently I noticed that the site is too slow and sometimes not loading at all and unfortunately I am not very familiar in solving issues like this and I don't have a system administrator who manages my dedicated server to contact with since I rent it from OVH which offers unmanaged servers in low cost. The server has pretty good specs and this issue happens even when there are 100 active users on site. I can also see some errors in my server logs.
Server specs are the following:
AMD Opteron(tm) Processor 4334, AMD Opteron(tm) Processor 4334 (6 core(s))
SoftRaid 3x160GB SSD
32GB RAM
1Gbps connection
CentOS x64 Linux release 7.2.1511 (Core)
Plesk v12.5.30
The errors I was talking about:

About fastcgi_params - I have no idea where to find this one on Plesk. I could only find a file with variables that I don't know their values.
Like these lines for example (that's how the whole file look like):
fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param CONTENT_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;
I am sorry if there's something missing, I really tried to make it detailed as possible and it's also not easy to find where the configuration files are located with Plesk. I had to do some research for each file I attached above... (That's one of the reasons I don't like Plesk to be honest, but that's what I have atm)
If there are any more configuration files you need me to send, please let me know and I will attach it in the comments. Please also let me know where I can find them (considering that I'm using Plesk v12.5).
It's really important for me to configure the server properly for my needs and for my specs and get rid of the errors, so please help me. :)
Thank you!
Try to increase your php-fpm children number, for example like this:
pm.max_children = 30
pm.start_servers = 10
pm.min_spare_servers = 3
pm.max_spare_servers = 15
then sudden spikes of traffic won't generate the error
make sure you have increased php-fpm backlogs variable:
listen.backlog = 100000
also increase the number of net.core.somaxconn=2000000 (kernel parameters at runtime).
like this :
sysctl net.core.somaxconn=200000
sysctl -p
I appear to be having an issue with my website when I browse around (just clicking links here and there), and my system would return a random 502 Bad Gateway error. I can hit the refresh button and it would appear to work fine.
