Issue with Ledger Browser (UI) disconnecting from nodes

[WadeBarnes]

After running for an extended period of time the Ledger Browser (UI) can loose its connections to the nodes. Typically a restart fixes the issue. However it would be nice to find a more permanent solution.

This causes a few issues:

• The validator node status stops working. The node status indicators (node circles) do not appear on the home page.
  • Under the covers the detailed node status is not collected, and since this is typically used to monitor the health of a von-network instance the ledger presents as non-functional (down).
• The DID registration controls stop functioning, since the connection to the ledger for writing transactions is lost.
• Ledger browsing functionality is lost, since connection to the ledger for reading is lost.
• From a client (agent) perspective the ledger typically continues to function without any issues, as it's only the Leger Browser's (von-network UI's) connection to the ledger that is affected.

@andrewwhitehead, Any initial thoughts on a fix or where someone could start?

Hi Wade, How much is "extended period of time"? weeks? months?

Thanks,

[WadeBarnes]

@Aberasturi, I've seen it run for months without issue, and I've seen it run into issues within a matter of weeks. It varies.

I see, hard to debug because it is at docker networking level and apparently not related to any timeout.
