The ministers will meet again at 0900 GMT today, just hours before for a summit of all 28 European Union leaders that is meant to be the final deadline for a deal to prevent Greece crashing out of the euro single currency.
"We have had an in-depth discussion of the Greek proposals, the issue of credibility and trust was discussed and also of course financial issues involved, but we haven't concluded our discussions," Dijsselbloem told reporters after some nine hours of tough talks.
Finnish Finance Minister Alexander Stubb was more upbeat, despite reports that Finland's parliament has decided it will not allow the government to accept any new bailout deal for Greece.
"We are making good progress," he said as he left the meeting just after midnight.

EU Commissioner for the euro Pierre Moscovici, who has been among the most sympathetic to Greece's plight, said: "I am always hopeful."
Ministers gave no details of the lengthy discussions yesterday but sources said there were sharp divisions over whether the latest Greek economic reform proposals go far enough to merit what would be a third bailout programme.
Germany has become increasingly frustrated with how Greece has implemented the debt programmes, demanding that it accept harsh austerity measures in return for fresh funding.
A German finance ministry document which came to light during the meeting but was not submitted to ministers said Berlin wanted many more concrete commitments from Greece before it could agree to a new bailout.
Failing that, then Greece should leave the eurozone for five years until it put its economic house in order, the document said, even though current rules appear to rule out such an option.
Spain, Italy, Malta were more conciliatory, as were Ireland and Portugal who like Greece also had to be bailed out at the height of the debt crisis.
