OSError micropython - micropython

Question

I get OSError on esp8266. First request is successful but second and more are failed with OSError, I dont know why. Can you help me?
Edit: I solved it. I wrote the solution at the end of the codes.
import network
name, password="wifiname", "passwordd"
wlan = network.WLAN(network.STA_IF)
wlan.active(True) # activate the interface
wlan.scan() # scan for access points
wlan.isconnected() # check if the station is connected to an AP
wlan.connect(name, password) # connect to an AP
wlan.config('mac') # get the interface's MAC address
wlan.ifconfig() # get the interface's IP/netmask/gw/DNS addresses
ap = network.WLAN(network.AP_IF) # create access-point interface
ap.active(True) # activate the interface
ap.config(essid='ESP-AP') # set the ESSID of the access point
print('Wifi connected! My IP:', wlan.ifconfig()[0])
import urequests
import time
while 1:
try:
t1=time.time()
r=urequests.get('https://saitamatechnoo.web.app/')
t2=time.time()
print(r.status_code, 'Time:', t2-t1)
except OSError:
print('error')
Guys, I solved it. It works with socket and we should close every socket after using it.
For example:
r=urequests.get('https://saitamatechnoo.web.app/')
print(r.status_code)
r.close()
