As mentioned in my first post, I tried several configurations, different browser setups etc, none of them working unfortunately, even not on other blockchain.com wallets/accounts. I still can't explain why this happend suddenly, because I didn't experienced any problems with blockchain the last months and I'm nearly using it on the daily. Tbh I would never to anything with BTC on my smartphone, I think this stuff should never be mixed up, but this is just my opinion.
Could be an internet-related issue rather than browser since you've tried different browsers, and PCs?
If it's only happening on one of your three accounts, then it's a different scenario.
I'm positive that the "
red error" on the right side should be the current BTC price next to the BTC balance.
Since it's 404, then there must be some important sources of the webpage that wasn't loaded.
Maybe it's an ISP issue or DNS issue since you've mentioned that it once fixed itself.
You can also try flushing your DNS cache or setting a different DNS server like Google's or Cloudflare's.
BTW, I second the suggestion to import your backup phrase to Electrum. That should enable you to send your balance unless it's in your "
Trading" or "
Interest Accounts".
