Ulster Bank have said payment problems suffered by some of its customers have now been fixed, after many were hit with technical difficulties on Thursday morning.
Customers reported payment and account problems this morning, just days after thousands were left unable to access their online systems or use banks cards.
It's understood some customers were having difficulty due to a backlog in delayed payments going through the bank systems.
A spokesman for Ulster Bank said a delay in "inward credit transfer files" for Euro payments had now been fixed.
The bank said transactions were now all through.
Earlier this morning, Ulster Bank said it was aware some were having issue with their accounts and was working to fix the problem.
On Thursday morning, dozens of customers facing account problems took to social media sites to vent their frustration.
Some reported issues with their online banking, as well as transferring funds.
Ulster Bank took to Twitter to try and alleviate the concerns of customers affected.
On its Twitter account, the bank said: "Some customers are experiencing issues this morning. We are working hard to get this fixed...it should be back up and running again very soon...Our online banking is very safe and secure to use, although we would advise caution."
Many customers claimed they were unable to access current transactions, wages being paid into accounts and other payments.
It is not known how many customers or payments have been affected by the glitch.
The latest technical difficulty to hit the majority state-owned bank comes after customers were unable to access their online systems or use banks during the busiest internet shopping day of the year.
The technology meltdown left customers of the Royal Bank of Scotland (RBS) Group, which includes NatWest and Ulster Bank, without the use of their debit or credit cards earlier this month.
The outage came on the busiest online shopping day - termed Cyber Monday - which typically boasts the highest amount of online transactions during the year.
Last week's short-term problems for bank customers came around 18 months after widespread computer problems left hundreds of thousands of people without access to their money.
That IT debacle cost the bank tens of millions of pounds.
Last year the financier revealed it set aside a provision of £82m to compensate the some 750,000 customers caught up in the IT failure.
In the wake of the glitch bank boss Jim Brown, defended a multi-million pound compensation package during the massive outage.
