Failed to create connection: SQLSTATE[HY000] [1040] Too many connections after upgrading to 1.4.0

Partially solved - now stuck on 500 error

For that part check this

Made change to maria conf, additional error now thrown by service worker, but still 500

(i also took down and restarted the whole stack)

Also tried on 127.0.0.1 - which did bring up the login prompt - but get 500 when trying to display dashboard

What are the logs from the main Appwrite

You'll need to clear the redis cache

Like so

Different errors, still 500

Can you try in incognito?

It's just a gash local install, so I can just wipe it - unless you want to investigate cause further?

What's easy for you

Incognito gives same problem

I will just wipe it

I did the following and it works for me

cd appwrite/
docker exec -it appwrite-redis redis-cli
flushall
exit
docker compose up -d --remove-orphans --renew-anon-volumes
docker compose exec appwrite migrate

thanks @Binyamin

it works and then it fail with another error Error: Error handler had an error: Pool 'console' is empty . I notice in the new .env file we have _APP_DOMAIN_FUNCTIONS= but it was empty, so I updated it to: _APP_DOMAIN_FUNCTIONS=localhost and now the app is running except for the functions Tab in the console, still shows 500

@Binyamin I didnt get round to wiping local install last night, then spotted that 1.4.1 was out, did a local migration to 1.4.1, and it came up without any 500s. Many thnaks
