When a Wallet Provider Cannot Reach the Requested Chain
A disconnected provider means a data or request path is unavailable. It does not establish that assets disappeared. Start by identifying which connection failed rather than changing account secrets or resubmitting an action.
Read the scope of the error
In the EIP-1193 provider standard, 4900 describes disconnection from all chains and 4901 describes disconnection from the requested chain. Those meanings apply when the provider returns the standard codes; a generic browser network error may contain less information. Missing account authorization is another category. Record the exact code and the named network rather than turning every failure into a general wallet-connectivity problem.
Compare independent observations
Check whether ordinary pages load, whether the wallet names the intended network, and whether an independently opened official explorer can display an existing public address. These observations narrow the problem without requiring a signature. An explorer loading successfully does not prove the wallet’s RPC works: the two tools can use different infrastructure. Conversely, an application quote endpoint failing does not mean every network data source is offline.
Change as little as possible
Pause repeated requests and review the existing provider settings against official network information. Do not install an extension or paste an unfamiliar endpoint offered by a pop-up. If an endpoint contains a private access token, exclude it from screenshots and reports. Avoid clearing browser storage as a first troubleshooting step because local wallet information may depend on it. Preserve a recovery plan before considering any destructive browser maintenance.
Preserve the last known transaction state
If a prior action produced a hash, retain it with its chain and observation time. A new lookup failure cannot cancel a transaction already broadcast. In RunixCoin, the selected wallet network and fixed Base quote request are separate contexts; report which view failed. A reasonable next observation is a later read-only lookup using the same public inputs. This guide does not report a current outage, endorse a replacement provider or verify live swap execution.
