Solution

Got a similar problem after changing base_url into phpMyAdmin: I accidentally saved value with tab and line ending characters before URL. I recomend to set again your base URL by using Magento's CLI:

php bin/magento setup:store-config:set --base-url="http://yourdomain.com/"

Also secure URL, if you entered it earlier:

php bin/magento setup:store-config:set --base-url-secure="https://yourdomain.com/"

Then flush the cache:

php bin/magento cache:flush
