I had this issue after AWS Lightsail snapshot restore. Way to restore a snapshot is to click on the three dots on side "create new instance" Then attach the the static ip. I observed redirect loops after this. (pain!!!) Later we figured out that the redirects was caused by the changes to urls as the base urls changed to IP address.

There are two ways to fix this. 1. via phpymyadmin > In AWS you need to connect via Putty with Key and tunnel via 8888 https://127.0.0.1:8888/phpmyadmin then on table core_config_data check the base url update base if IP address. then change. web/secure/use_in_frontend set value from 1 to 0 web/secure/use_in_adminhtml set value from 1 to 0

Then clear magento cache.

2. via cli.

/opt/bitnami/apps/magento/htdocs/bin# ./magento-cli cache:flush Flushed cache types: config layout block_html collections reflection db_ddl compiled_config eav customer_notification config_integration config_integration_api full_page config_webservice translate vertex

I've recently had the chrome redirect loop on gmail.

Possibly significantly, I was doing some work involving changing my system time and it hasn't worked since. This guide helped to do that.

There is an available work-around, which is to use gmail in incognito mode, which does still work, although requires you to log in each time
