If I trt to create filter for my contract using ropsten.infura.io websocket server, all works fine.
With mainnet.infura my request to createFilter just hangs and eventually times out.
I guess my question is - can I create filter using mainnet.infura.io websocket?
Thank you
Hello,
We have filter support on mainnet as well as ropsten. I have used wscat to test out filters on mainnet and also created a quick web3js sample. I can confirm that filters are working. As you can see from the screen capture I am getting the logs (all the way at the bottom that’s been cut off) (I didn’t know if you wanted to keep the contract and logs hidden so I purposely left it out of the screen capture but I used the address that was in the other thread Does or does not Infura support websocket? I'm confused - Questions - Infura Community)
OK, that works for me, yay! 
Btw, check out what i coded - it’s called a cryptodice2 (utilising random.org) .
Let me know what your thoughts are.
Thanks!
