Occasionally OTA's have issues where their servers are unable to process updates that we send them.
If you see an error on the dashboard or in an email that has a code 500, 501, 502, 503 OR mentions 'Internal Server/System Error' you can go to Settings > OTA Connections and click through to the affected connection. Then click either:
Sync Availability (for failures following availability or booking changes)
or
Sync Rates (for failed updates related to pricing).
If you are unsure what type of message failed, you can click Sync All (both Availability and Rates) but this will send far more information than is needed and will take far longer to process.
The Sync Out Logs will then display whether that manual sync has been sent successfully. (Note: this may take a few minutes to process).
If this results in the same error a second time, please DO NOT keep repeatedly attempting to manually resynchronise your availability or pricing. Chances are the OTA is having an outage, and the update won't work, and in fact could slow down updates to other OTA's who are not experiencing problems. Wait for 20 minutes and try to close out one room (or make a spot change to pricing for one night). If that update is successful, then it would appear the outage is resolved and you can retry again with a Sync.
If you desperately need to close out to Expedia, it is possible to manually close a date, or date range, from within the Expedia Extranet. Booking.com does not support updating from any source other than the channel manager, so in this case you would just have to wait until their issue is resolved.
