What does it mean when your broker says my buy failed due to a liquidity problem ?

I woke up to Brexit luckily I had been smart enough to A) Move most of my money from Pounds sterling into the Dollar B) was very light on UK stocks. I saw Lloyds bank shares going for a song put in a fill or kill that just sat there cancelled that put in a buy at market rate that came back failed. Rang the broker and after half an hour waiting in a queue they said there was a liquidity problem. Is this the broker running out of funds or just my country (UK) running out of funds? Eventually got my shares but not after they had gone up considerably. Oh and don't blame me for the exit I voted the other way.
