Yes, it's caused by out of date E-Ticket decoding pubkeys. RDG provides access for these to be pulled down from a private API and recommends this is done every 24h, but for whatever reason Ticketer isn't actually doing that today and the buses are left with a stale set of keys, which means they cannot decode many tickets.
For what it's worth, the forum site submitted the underlying barcode key that's used when issuing these tickets back in summer 2023, so it's not likely it recently changed.
I have been talking back and forth with technical support at Ticketer about this over the last few weeks, following some assistance from a really helpful bus operator in one specific area who was willing to thoroughly test it and escalate the problem, working with Raileasy. We've got it fixed in a couple of places now across a couple of operators, but Ticketer can't just do a sweeping update across the all of their operators in one go for reasons I don't entirely understand, and fixes need to be applied in each broken area.
If you've experienced issues, I am told that what's important is:
- The exact timestamp at which the PlusBus ticket was scanned and rejected by the bus
- The specific operator and route number
- If you know the vehicle details, these are useful too - these can be looked up on https://bustimes.org
Please submit these to TrainSplit customer support and I will compile the issue reports and send over to Ticketer. Please do not send reports about:
Manchester (Metroline)
- We are told this has been fixed. Please do send reports if issues are experienced.
Redhill (Metrobus)
- We are told this has been fixed. Please do send reports if issues are experienced.
- Ipswich (Ipswich Buses)
- Glasgow (McGills)
Burgess Hill (Compass Bus)
- We are told this has been fixed. Please do send reports if issues are experienced.
- Derby (Arriva)
As all of these areas are (or were at one point) broken and have already been reported.
For First Bus, we have been made aware that the following areas have been fixed very recently:
- First West Yorkshire
- First South Yorkshire
- First York
- First Leicester
- First Aberdeen
- First Eastern Counties
Reports for other First Bus areas are now useful and welcomed.
Obviously this is only relevant if the bus ETM is supplied by Ticketer.
