Title: Bad gateway (Error code 502) Last modified: November 8, 2024 --- # Bad gateway (Error code 502) * Resolved [User](https://wordpress.org/support/users/lostguybrazil/) * (@lostguybrazil) * [1 year, 7 months ago](https://wordpress.org/support/topic/bad-gateway-error-code-502-2/) * Hi, First thank you for this amazing plugin.On a recent update I have started noticing that in 2 of my websites I get an _“Bad gateway (Error code 502)”_ when trying to open the Media Library page (Media > Library) (/wp-admin/upload.php). When I deactivate the “Phoenix Media Rename” plugin, the Media Library works normally as expected.I tried to check the logs (have both `define( 'WP_DEBUG', true );` and `define( 'WP_DEBUG_LOG', true );` activated in my wp-config.php file) but I don’t see anything that could help me investigating this issue.Kind regards Viewing 15 replies - 1 through 15 (of 16 total) 1 [2](https://wordpress.org/support/topic/bad-gateway-error-code-502-2/page/2/?output_format=md) [→](https://wordpress.org/support/topic/bad-gateway-error-code-502-2/page/2/?output_format=md) * Plugin Author [crossi72](https://wordpress.org/support/users/crossi72/) * (@crossi72) * [1 year, 7 months ago](https://wordpress.org/support/topic/bad-gateway-error-code-502-2/#post-18122325) * Hi [@lostguybrazil](https://wordpress.org/support/users/lostguybrazil/), since version 3.12 Phoenix Media Rename uses cookie, maybe this can create some compatibility issue with other plugins, can you tell me which plugins you are using, so that I can try to replicate your configuration on my development server? * Thank you for reporting C. * Thread Starter [User](https://wordpress.org/support/users/lostguybrazil/) * (@lostguybrazil) * [1 year, 7 months ago](https://wordpress.org/support/topic/bad-gateway-error-code-502-2/#post-18122611) * Thank you for your quick response! I currently have 4 websites running the latest version of “Phoenix Media Rename” (v3.12.6). On 2 of these websites, I am encountering the issue described in the original post (OP). * Here are the plugins installed on one of the problematic websites: AAA Option Optimizer – 1.2.1Admin and Site Enhancements (ASE) – 7.5.1Advanced Database Cleaner PRO – 3.2.10Brazilian Market on WooCommerce – 4.0.2Cloudflare – 4.12.8Complianz | GDPR/CCPA Cookie Consent – 7.1.4Connect Polylang for Elementor – 2.4.5CTX Feed– 6.5.31Easy Auto SKU Generator for WooCommerce – 1.2.0Edit Custom Fields – 0.1.10Elementor– 3.25.4Embed Google Fonts – 3.1.1Google Analytics for WooCommerce – 2.1.7Matomo Analytics – Ethical Stats.

This could be only a coincidence. * Thanks again! * Plugin Author [crossi72](https://wordpress.org/support/users/crossi72/) * (@crossi72) * [1 year, 7 months ago](https://wordpress.org/support/topic/bad-gateway-error-code-502-2/#post-18122738) * Hi [@lostguybrazil](https://wordpress.org/support/users/lostguybrazil/), I’ll try to replicate your configuration on my server, I hope to find the issue soon. * I tested Phoenix Media Rename on a site with more than 4000 images and 100 file per page in media library and everything works, so the number of images shouldn’t cause any problems. * Thank you for your help addressing this issue C. * Plugin Author [crossi72](https://wordpress.org/support/users/crossi72/) * (@crossi72) * [1 year, 7 months ago](https://wordpress.org/support/topic/bad-gateway-error-code-502-2/#post-18123035) * I’m trying the plugins you listed, but at the moment everything is working, can you check the server log and tell me which line of Phoenix Media Rename is reported there as the one that caused the crash? * You can find the error log in the administration panel of your hosting. * C. - This reply was modified 1 year, 7 months ago by [crossi72](https://wordpress.org/support/users/crossi72/). * [wonderwooman](https://wordpress.org/support/users/wonderwooman/) * (@wonderwooman) * [1 year, 7 months ago](https://wordpress.org/support/topic/bad-gateway-error-code-502-2/#post-18124236) * This also happened to my site right after upgrading a few plugins a few hours ago. Everything works fine after deactivating this plugin. It doesn’t occur on the staging site where I haven’t made the upgrades. * No error log is recorded on the hosting side. - This reply was modified 1 year, 7 months ago by [wonderwooman](https://wordpress.org/support/users/wonderwooman/). * Thread Starter [User](https://wordpress.org/support/users/lostguybrazil/) * (@lostguybrazil) * [1 year, 7 months ago](https://wordpress.org/support/topic/bad-gateway-error-code-502-2/#post-18124559) * Hi [@crossi72](https://wordpress.org/support/users/crossi72/), thank you for checking the plugins and replicating my setup. For the WordPress Debug file, I don’t see anything related to this issue.For the server log file, I have noticed that this entry is added to the log every time I try to open the the Media Library page (Media > Library) (/wp-admin/upload.php) (the number `*314044` changes slightly on every entry): “nginx error: 1588306#0: *314044 upstream sent too big header while reading response header from upstream”.Maybe it helps!Kind regards * Plugin Author [crossi72](https://wordpress.org/support/users/crossi72/) * (@crossi72) * [1 year, 7 months ago](https://wordpress.org/support/topic/bad-gateway-error-code-502-2/#post-18124566) * Hi [@lostguybrazil](https://wordpress.org/support/users/lostguybrazil/), that message is quite useful: the new version on Phoenix Media Rename uses cookies instead of database to store temporary data and I think that some hosting doesn’t supports all that data. * I’ll dig into this and let you know as soon as I will find a fix. * Thank you for you help C. * Thread Starter [User](https://wordpress.org/support/users/lostguybrazil/) * (@lostguybrazil) * [1 year, 7 months ago](https://wordpress.org/support/topic/bad-gateway-error-code-502-2/#post-18124581) * Hi [@crossi72](https://wordpress.org/support/users/crossi72/), * Thank you for the quick response! I wanted to provide a bit more information: three of the websites mentioned are hosted on a VPS Debian server. Out of these, two websites are experiencing the issue, while one is not. This leads me to believe that the problem might not be related to hosting limitations, as one of the sites is functioning correctly. * Thanks again for your help! * Plugin Author [crossi72](https://wordpress.org/support/users/crossi72/) * (@crossi72) * [1 year, 7 months ago](https://wordpress.org/support/topic/bad-gateway-error-code-502-2/#post-18125031) * Hi [@lostguybrazil](https://wordpress.org/support/users/lostguybrazil/), I’m working on a new version that doesn’t use cookie, if I have the error correctly this would resolve your issue. * I hope to complete development and tests in a couple of days, I will let you know as soon as I will release it. * C. * Thread Starter [User](https://wordpress.org/support/users/lostguybrazil/) * (@lostguybrazil) * [1 year, 7 months ago](https://wordpress.org/support/topic/bad-gateway-error-code-502-2/#post-18125106) * Hi [@crossi72](https://wordpress.org/support/users/crossi72/), many thanks for the update and for the great support!
