Not working first primary master makes UI unavailble

[kaikash]

Hello!

In case when first primary master doesn't work it makes UI not available, api/cluster-params/<cluster> fails with error

Oops! something went wrong. If the problem persists please report it via Bug Reporter.

It always takes the first master and makes get request to its orchid and this request fails with Connection timed out error. Seems to be because of this:

ytsaurus-ui/packages/ui/src/ui/store/actions/system/masters.ts

Line 113 in c849ecb

const [primary_path] = [...Object.keys(ypath.getValue(primaryMasterResult.output))];

Are you using address of your primary master as proxy-field in your cluster-config.json?
UI uses the field for all requests (except heavy ones).

No, we are using http proxies for all communication between UI and YT. In turn, http proxy makes requests to first master orchid, which can be unavalable.
