Interpretation of log file events:

10:01:26 new offer is entered, fee is estimated @ 4160 bytes (16 sats/byte)
10:28:26 funds received from external source
10:30:31 offer is confirmed by user, fee is estimated @ 4680 bytes (18 sats/byte)
error pops up due to insufficient funds 520 sats missing
4680 - 4160 = 520 (missing amount).

Summary: fees rose in between making the offer and confirming it. Since funding was exact amount from an external wallet, the extra sats were not available to make the transaction.
