Hi all,

I have a problem after upgrade to Magento 2.3.5 p1, showing bad gateway after create customer account and can not save new product.

in log:

main.DEBUG: cache_invalidate: {"method":"GET","url":"/","invalidateInfo":{"identifier":"LOCKED_RECORD_INFO_BLOCK_585e012f5f1020b2bdf1be798f49fb2710f6465d"}} [] 

and

main.DEBUG: cache_invalidate: {"method":"POST","url":"/productfilter/index/firstLoad/","invalidateInfo":{"identifier":"LOCKED_RECORD_INFO_BLOCK_528da0c324e82b2f56746cd022625b5e68c6d930"}} []

Hi @fajriarma ,

Please enable developer mode in you instance to check the error using below commad.

php bin/Magento deploy:mode:set developer

 And also add below line in your index.php for checking the errors.

ini_set('display_errors', '1');ini_set('display_startup_errors', '1');error_reporting(E_ALL);

Hope this helps you!

@fajriarma 

Can you check server configuration like: output_buffering, fastcgi_buffers, fastcgi_buffer_size are correct or not.

Or please try to check by disable full page cache from admin magento.
