Hey, there are two different things:
- API access, that endpoint doesn’t change, it’s just requiring authentication, so your ipfsclient should only add auth if is not using already. See an example here How to add files using ipfs-http-client
- accessing files through the gateway - the public one ipfs.infura.io has been deprecated and you’ll need to use the dedicated one for that, so if you’ve previously been accessing a CID with this
https://ipfs.infura.io/ipfs/CID
now you’ll need to create a dedicated gateway and access it via:
https://<your_gw_name>.infura-ipfs.io/ipfs/CID
Note: don’t start <your_gw_name> with “ipfs”, we have a slight issue with that that’s going to be addressed soon. 
It worked …Thankyou so mach man…
