Cannot Save a View without getting 502 Bad Gateway Error [#2448227]

Drupal 7.34 on Pantheon server.

I've been having a really difficult time with my Drupal site the last couple of weeks. I had to renew an SSL certificate and once I did, I started getting Bad Gateway 502 errors everywhere.

It's a pretty robust site as it runs our whole business.

There were no new modules or updates for a couple of weeks - everything was working great, it just started giving these errors after the new SSl certificate was updated.

Basically when I try to update and save a View, it goes to a 502 Error Nginx screen. I can't refresh or go to another page - I have to restore the site from the server to a previous backup.

When I refresh the cache, enable disable a module, edit a registration, add comments in a forum - I also get a 502 Bad Gateway message but refreshing the browser will allow the site to reappear continue working.

I understand this may not be all views but that is the one thing that locks the site up 100% of the time.

The server logs don't show any errors (that I can tell). Basically everything looks to just stop (all logs) after the 502 happens.

I've built quite a few Drupal sites but am not familiar with php or server side issues so any suggestions would be very helpful.

Hi Michael, how are you?

In Acquia, it works good but for this question, I checked with some contacts that using Phanteon with Drupal and Views and works good with Views 7.x-3.18.

I'm checking in Pantheon and exists this information about it:

"There was an error connecting to the PHP backend." If the php-fpm process hangs or cannot start, Nginx, the web server will report this problem.

https://pantheon.io/docs/errors-and-server-responses/

I suggest that you update for the last version of views and Drupal Core -> create a dump file of your database -> run update.php and try again. If persist check Drupal logs watchdog in admin/report/dblog if not exists any log, I recommend you contact the webhost for we check the logs about webserver. This can help.

Thank you very much Michael.
