Hello, again Chris
I have done as suggested, ie restored the file OFFLINE, cleared all invoices sitting in both the 'unprinted' and 'unsent email' lists. Checked that advanced filter is ticked for 'unsent only'. Restored that file back ONLINE.
After doing that after hours last night, I WAS able to open the print / email invoices section (noting that there were no invoices appearing in the lists on opening as they'd been cleared). HOWEVER, this morning we are back to getting the same 'Unable to connect' error message as before.
So... not fixed.
I note that when I managed to access the lists offline that there was NOT a huge number of invoices in there appearing as unsent...maybe 100 or so... (this would be because we have been - tediously! - opening each invoice and emailing them one by one at the end of each day, plus all invoices are printed on creation)... and that the advanced setting was already checked for 'unprinted/unsent invoices only'. So I'm not convinced it's a volume issue as suggested, as previous to this problem arising in June we were routinely able to access the lists with more invoices that that sitting in there, without issue.
I eagerly look forward to your solution to this problem, as it continues to waste a lot of staff time & it is not feasible for us to contine like this.
Thank you.
Hello Coral3
It could be a timeout issue while the file is online, I would suggest the following this post guiding how to extend the timeout extender.
I would also suggest flushing the DNS cache as this could also be impacting it since it isn't working online but working locally.
