(Hello), I'm having some issues with Bitcoin Core, it is sync with community and the ETA suddently starts to increase. Now it shows 5 weeks, but it increases randomly. I think my internet connection is fine because all webpages and services load well and fast. Someone knows what can I do or something similar? Thanks for your help. Recently I synced with an slow internet connection in 2 days, some especial situation? Transactions volume?
