I think you can only fix it if you have your own full node or ElectrumX server where you can able to edit the minimum relay fee because most of the nodes or servers listed on Electrum only have a relay fee of 1 sat/vbyte lower than that I think no server offers lower than the current minimum fee but you can try to find server under "green circle" change your server and try to send.
Or your last hope is to have an ElectrumX server where you can able to edit the minimum relay fee.
