Error 406 when importing csv file under leads entity

[Casey41]

when trying to import csv-UTF-8 encoding, browser throws error 406,

[2020-01-09 20:17:04] Espo.ERROR: WebSocketSubmission: Class 'ZMQContext' not found [] []
[2020-01-09 21:34:03] Espo.ERROR: CronManager (ScheduledJob [5e12e285574e4f539]): Scheduling string error - 0/2 is not a valid CRON expression. [] []

I went into my php.ini files and set up ZMQ websocket correctly and tried to import and it gave me the same CronManager scheduled job problem

Any suggestions?

Hello,
the schedule for CRON is not valid. Such a schedule as 0/2 is wrong. Fix it please. Or tell me please what schedule are you trying to set to let me help.
