Why was my Bitcoin deposit rejected?

I'm a crypto enthusiast who's just encountered a rather perplexing issue. I was attempting to deposit some Bitcoin into my digital wallet, but the transaction was unexpectedly rejected. Could you please elaborate on the possible reasons behind this rejection? I've double-checked the wallet address and ensured that I have sufficient funds in my Bitcoin account. I'm also certain that the network fees were appropriately set. Could the issue be related to the wallet's specific settings or perhaps a broader issue with the blockchain? Your insights would be greatly appreciated.
