Hi there!
Stack with the problem that the indexer on the MainNet works somewhat unstable, I will explain why:
Had a CORS problem using https://indexer.algoexplorerapi.io as the indexer URL, so had to use https://algoindexer.algoexplorerapi.io and it works! However, after some time I started getting 404 from the indexer with the message
{
"message": "no accounts found for address: O3BX55FOVNLTL3MTZ2SRPOSUXPW44X3YKOTMIBBZ24WLRJ2YEAN3XEHYBU"
}
and this happens at random intervals.
Although I have these accounts in my Algosigner wallet and also Algoexplorer can find at own site.
Also funny thing: indexer back me 404 only for 3/4 accounts 
. Image below:
To be sure, I sent a request with the same account address to https://indexer… and got 200 in response.
Tell me please what this can be connected with and how to solve this problem.
