Origin not able to connect to blockchain network using Metamask extension

The log indicates there was a problem - 400 code coming from backend service. Can you post log of yarn run:backend?

Also, before deploying new demo, please remove the backend database first. For example, instead of running yarn run:backend from root directory, run:

rm -rf db.sqlite && yarn start:dev

from inside packages/origin-backend directory

[Kuzirashi]

So, after you deploy demo once, then you need to clear database and restart origin-backend. The easiest way to do it is to find db.sqlite and remove it.

@RohitGupta027 Can you post the log of yarn run:demo command?

Worked like charm by running rm -rf db.sqlite && yarn start:dev from project directory. Earlier I started the backend from the root directory and it does start without any error but then yarn run:demo was giving error 400 . Any idea what causes the issue before?

Thanks @Kuzirashi for your quick responses and provide solution.
