As per announcement, we need to switch our Infura project IDs.
> As previously announced, accessing Infura will begin requiring a Project ID generated from the new Infura Dashboard. If you are using Infura and have not yet migrated your project, please take the time to do so now. The first milestone in this transition will be activated next week on January 23, 2019 at 20:00 UTC.

The new project is created with ID `f315575765b14720b32382a61a89341a`
and the API keys are updated.
