Please help me about error "Off quotes"

 

I Subcribed 1 Signals, They opened 1 position but after that time about 2 hours, my Account opened the same position ( At very different PRICE). 

I closed that position manually, then MT4 automatic opened other position (Because the signals still opened their position): 

2021.07.28 09:25:21.303 '11545384': Signal - local position [#334338755 sell 0.01 GBPCAD at 1.74658 tp: 1.74226] is equal to the signal one [#7110658 sell 0.05 GBPCAD at 1.74955 tp: 1.74226], no changes are made

2021.07.28 09:25:21.303 '11545384': Signal - synchronization finished successfully


But after about 10 minutes:

2021.07.28 09:34:27.857 '11545384': modification of order #334338750 sell 0.01 GBPCAD at 1.74658 sl: 0.00000 tp: 1.74260 -> sl: 0.00000 tp: 1.74249 failed [Off quotes]

 2021.07.28 09:34:27.857 '11545384': Signal - trade request failed [Off quotes]

2021.07.28 09:34:27.857 '11545384': Signal - synchronization failed, processing of trade actions disabled



PLEASE HELP ME, HOW CAN I FIX THAT ERROR
